How to compare to a numeric value in a SharePoint column

I have a PowerApp that writes to a SharePoint list. This app is intended to track a back-and-forth discussion, and to keep the records readable I have a column in SharePoint called Trip#. Each time the form is updated and saved that number increments by 1.


All of this works, but I have a series of hidden dialogs that I want to become visible one by one as the number increments, so the visible property for the first one would be TRUE if > 2, and the next one TRUE if > 3. The column is in numeric format, not text. 

 

This should be super easy, but I am a major newbie and using .Value or other command variations nets me an Invalid Argument Type error every time.

SORRY! My command was correct, and I knew it had to be on the actual text box, but somehow I didn't read correctly and was thinking the name of the data card holding the text box was the text box proper. In other words, I messed up and entered the wrong name.

 

Once I corrected that it started working. Thanks all!

Any time you have a "number" that is in string form (which will be the case many if not most of the time) you will want to use the value function. For example if you have "1234" stored in a var called stringNumber and want to Patch it to SP use:

Value("1234") 

This will take the string given and, if valid/possible, will convert it into a number

How are you getting the numberIncrement? Without seeing the data and code, I would suggest trying Value(numberIncrement).

Well, I am incrementing the number via the code below.

 

If you mean how am I getting the number into the "visible" variable I suspect that's part of the issue (i.e., I am doing it wrong).

 

With(
{wNo:ThisItem.'Trip#'},
Patch(
Support,
ThisItem,
{'Trip#': wNo + 1}
)
)

So here is what I tried, noting that "Support' is the name of the SharePoint list and "Trip#' is the specific column:

 

If(Value([@Support].'Trip#') > 1, false, true)

 

I get an error "Expected text or number" for this line. 

 

What is the result if you add a textbox with the formula Value([@Support].'Trip#').  Does that return a number?  Also where is your field that you want to become visible?  Is this in a Gallery, a Form...?

Sorry to answer a Q with a Q, but if I add the field in as a data card it displays the number correctly and increments too. Maybe I can just read that data card for the value instead? If so I can make that data card not visible and it would be the same, no?

You can certainly do that since the value in the data card can be used outside of the form. I'm guessing your dialogs are outside of the form, so that's why you're having trouble using the trips value.

Is the context different? The data card that actually has the numeric is called Trip#_DataCard, but if I use this IF statement I get a "Name isn't valid" error: If(('Trip#_DataCard') 1, false, true)

 

I also tried If(Value('Trip#_DataCard'.Text) 1, false, true) but get the same error.

It depends on what type of object Trip#_DataCard is. If it's a TextInput or Label, then what you have in your last sentence is correct. You are only missing the ">" before the "1".
