Hello Guys/@yashag2255,

If(Value(DataCardValue9.Text) > Value(compassionateleavebalance.Text),true, false )

in app testing it works well, but when published it does not work well, the error message displays when any digit is typed into the (DatacardValue9.Text) field even if it is actually less than the DataCardValue9.

Please help guys

Can you try this and post a screen shot of the result? Please make 2 new labels and input the following in the Text property of the labels:

DataCardValue9.Text
compassionateleavebalance.Text

Are they the values you expected? Send us a screen shot showing the labels and the error message.

Yes they are values expected,
the app works well as expected when running a test while in power apps
but after publishing the application, while trying to run it as an ordinary user the comparison does not work well then.

That error message should only show up if the value inputed is greater than the annual leave balance which is 15 in this case
i typed in '1' in the field and thats the outcome first is testing while designing second is testing after publishing to the intranet (same account)

Testing the app while in powerapp designtesting the app running it as a separate app

I think the problem is it takes a longtime for the value of Value(compassionateleavebalance.text) to be gotten, because after a while of waiting on the page, the app works in order.

i called the Value(compassionateleavebalance.text) from a label (ThisItem.'compassionateleavebalance') in a gallery whose data source is 'Leave Balance List' on another screen,
how can i make the app load faster?

Using variables or collections to store data in memory is a common way to improve app performance rather that calling it from the datasource each time.

From what I understand your app has 2 screens. Screen1 has a gallery and the user selects an Item to Navigate to Screen2. Add the following code to your gallery's OnSelect property

Navigate(Screen2, None); Set(CompassionateLeaveBalance, Value(ThisItem.'compassionateleavebalance'));

Then on Screen2, change the Visible property of your error message to:

If(Value(DataCardValue9.Text) > CompassionateLeaveBalance,true, false )

If your theory about the app being slow to load is correct I think my approach will work. Let me know.

@mdevaney
Is there i a away i can load it onstart of the application.

There is a list called Leave Balance List with different users and their leave balance, here we have Annual Leave Balance, Sick LeaveBalance and Compassionate Leave Balance.

There is another list where all leave applications are submitted (Leave Applications)

Both lists have Staff Names.
How can i call the app to pick the all the values of Leave Balance (Annual, Sick, Compassionte) on start of the application for the current user logged on. this way it might just be faster.

To pick the all the values of Leave Balance when the application loads put the following code into the OnStart property of your app

Collect(LeaveBalances,First(Filter(your_leave_balance_list_name,UserName = User().FullName)));
Set(AnnualLeaveBalance,LeaveBalances.your_annual_column_name);
Set(CompassionateLeaveBalance,LeaveBalances.your_compasionate_column_name);
Set(SickBalance,LeaveBalances.your_sick_column_name);

You'll want to understand how the User() function works. User().FullName returns the current user's full name in the format below. You will have to have a matching column called UserName in the Leave Balance list.

Andrew Bernard

Alternatively, you could try User().Email instead. This would ensure everyone has a unique ID (example: two people might have the same name Jim Smith).

Hi @mdevaney

i have this now

Collect(LeaveBalances,First(Filter('Leave Balance List','Staff Name'.Email = CurrentUserEmail)));
Set(AnnualLeaveBalance,LeaveBalances.'Annual Leave Balance');
Set(AnnualLeaveBalance,LeaveBalances.'Sick Leave Balance');
Set(AnnualLeaveBalance,LeaveBalances.'Compassionate Leave Balance');

No errors now how do i do the comparison now in the visibilty property of my error message

initially it was

If(Value(DataCardValue14.Text) > Value(Label4.Text) ,true, false) it was working but was delaying at startup
value in red hold the value of the annual leave balance of the logged on user

Now how do i use the collected value 'AnnualLeaveBalance' of the current user in that expression

if(Value(DataCardValue14.Text) > ............ , true , false) please help fill the blanks using the collectd value

Your code here does not match mine.

Collect(LeaveBalances,First(Filter('Leave Balance List','Staff Name'.Email = CurrentUserEmail)));
Set(AnnualLeaveBalance,LeaveBalances.'Annual Leave Balance');
Set(AnnualLeaveBalance,LeaveBalances.'Sick Leave Balance');
Set(AnnualLeaveBalance,LeaveBalances.'Compassionate Leave Balance');

You need to use 3 different variable names instead: AnnualLeaveBalance, SickLeaveBalance, CompassionateLeaveBalance

Then, assuming DataCardValue14 refers to sick leave requested you would use:

if(Value(DataCardValue14.Text) > sickLeaveBalance, true , false)

@abieba
That means you are comparing a Number to something else (e.g. Text) in your If statement. Try putting SickLeaveBalance inside a Value() function

If you want to see what the collection looks like during troubleshooting just put it in a Data Table temporarily. Similarly you can put the Set variables in Labels temporarily. Just to see their values.
