Variables Assignment Issue

Posted on by Community Power Pla... Microsoft Employee

I have a strange and specific issue that is making the value of my variable 0 no matter what number is written in the text box it is coming from. There are a few layers to this and I will explain below, any help is appreciated.

In the OnStart property of the App, I have a variable declared as this:

Set(varIncrement, Value(Last(DowntimeDB).Title))

This variable is then assigned to the text input "txtNumber_3" as Value(varIncrement).

Upon clicking a button, varIncrement increases by 1 value using this code:

Set(varIncrement, varIncrement + 1)

The problem begins here. I am trying to create a new variable from the value inside txtNumber_3 for another screen, the code is:

Set(varExtraIncrement, txtNumber_3.Text)

When I try to assign this new variable to a new text input, the value is always 0 no matter what. Am I doing something wrong throughout this whole process of variable overriding? Again, any help would be appreciated as I'm stuck!

Thanks.

Where are you doing the create for your second variable? I just did a mockup of your issue and it works fine for me if I set the variable as I navigate to the next screen like this

Set(varExtraIncrement, TextInput1.Text);Navigate(Screen1,ScreenTransition.Fade)

@Pstork1 thanks for the response. In the first screen before proceeding to the next screen, I have a Proceed button. Here in the Proceed button, I am declaring the new variable varExtraIncrement, just as you have shown in your response.
I then put Value(varExtraIncrement) in the text input on the next screen, the value always being 0.

I'm still unsure why this is happening.

AS you can see from my code I'm doing the same thing and it works on my setup. Is that the only Set you have for VarExtraIncrement? Or could it be being reset by some other action?

No, varExtraIncrement is being set only once in the Proceed button. I am sure it is not being reset anywhere as the code I have shown in the initial question are the only places varIncrement and varExtraIncrement are declared and manipulated in the app.

Could it be something to do with varIncrement being overwritten to increment the variable by one? Or is that not the issue?

That shouldn't be an issue unless you are trying to increment it at the same time you are setting varExtraIncrement. As I said, I'm not able to reproduce your issue. It works fine in my setup so I'm not sure how to help.

This actually seems to be the issue. The Proceed button contains the code for both incrementing varIncrement and setting varExtraIncrement. I will experiment with this now and see if I can resolve it. Thank you for your help.

This worked well. I placed the code for declaring varExtraIncrement elsewhere and it worked. Thank you for your help!
