Hi Team,

I'm needing help with an IF/IF-AND statement. I want the button to be disabled if two conditions are not met. The conditions are:

1. A dropdown box value is selected

2. A form is valid.

I am able to have the button work just running with the condition: If(Form1.Valid, DisplayMode.Edit,DisplayMode.Disabled)

So I am naturally trying this with no success:

If((IsEmpty(DataCardValue39.SelectedItems.Value)) & (Form1.Valid), DisplayMode.Edit, DisplayMode.Disabled)

& is the string concatenation operator.
&& is the boolean and operator.

I suspect you want the latter.

So Sorry,
So this: ?
If(Len(DataCardValue39.Selected.Value) = 0 && Form1.Valid, DisplayMode.Edit, DisplayMode.Disabled)

The button stays disabled, I believe that it's not detecting the dropdown selection.

Highlight DataCardValue39.Selected in your editor. What does it show?

The selected value. (Data Type: Record). I think it's detecting 0 as a number and not blank?

I would try:
If(IsBlank(DataCardValue39.Selected) && Form1.Valid,DisplayMode.Edit,DisplayMode.Disabled)
If(IsEmpty(DataCardValue39.SelectedText.Value) && Form1.Valid,DisplayMode.Edit,DisplayMode.Disabled)

Also it might be worth trying without "&& For1.Valid" to ensure you're getting the right behavior related to DataCardValue39, i.e. you're not looking in the wrong place.

Sorry still no luck, the alternative is that Form1 has two dropdowns which I am also relying on being entered before the button becomes active.
Would there be a way to do something like the following?

If((IsEmpty(DataCardValue39.Selected.Value) & (IsEmpty(DataCardValue20.Selected.Value) & (IsEmpty(DataCardValue30.Selected.Value)))),DisplayMode.Edit,DisplayMode.Disabled).

Until all three dropdowns are selected then be DisplayMode.Edit on the button?

Hi @notepadapp ,

I hope your datacard is actually a dropdown control, if yes try the following code:

If( (!IsBlank(DataCardValue39.SelectedItems) && !IsBlank(DataCardValue39.Selected.Value)) && Form1.Valid, DisplayMode.Edit, DisplayMode.Disabled )

Hope this helps
