Hi,

When i'm trying to set a variable on multiple screens i get this error message:

Incompatible type. We can’t evaluate your formula because the context variable types are incompatible with the types of values in other places in your app.

Here is the Variable i use;

Set(PDD1;TextInput4_42.Text)

and the other variables set also to "PDD1"

Set(PDD1; If(CountRows(colNCOLIS) >= 1; First(colNCOLIS).Weight; Blank()))
Set(PDD1; If(CountRows(colNCOLIS) >= 1; First(colNCOLIS).Weight; Blank()))

One of these variables is located on OnTimerEnd of a timer control and the two others a select of a button control.

What does this error means? and how to avoid this kind of error next time?

This variable is used to show weight values on a label control.

Hi @Sormick,

What type of field is Weight ? If it is a number, then the first one should be
Set( PDD1; Value(TextInput4_42.Text) )

The second should work, but this may be better
Set( PDD1; If( CountRows(colNCOLIS) >= 1; First(colNCOLIS).Weight; 0 ) )

Hello,

The error means that you for example first set your variable to a text value, and in another place, you set it as a number value. This is not allowed. A variable must be the same type everywhere in your app. So in your case, if you do for example:

Set(PDD1;Value(TextInput4_42.Text))

it should work. Because then the variable is always a number.

This value is a number with two decimals get from a sharepoint list with the creation of a collection:

ClearCollect( colNCOLIS; FirstN( ShowColumns( Filter( CP78RECTIFCP87; Dispatch = Label11.Text && OBSERVATIONS = "MISSING" ); 'Item ID'; Weight; 'Destination Country' ); 10 ) )

and set this variable to get the weight value of my collection colNCOLIS

Set(PDD1; If(CountRows(colNCOLIS) >= 1; First(colNCOLIS).Weight; Blank()))

This weight must be shown on a Label on a form.

Now i'm trying this function to get the new weight for my new textinputbox:

Set( PDD1; Substitute( Text( Value(TextInput4_42.Text); "[$-fr-FR]0.00" ); "."; "," ) )

But i still get the same error:

Incompatible type. We can’t evaluate your formula because the context variable types are incompatible with the types of values in other places in your app.

Hi @Sormick,

OK - the issue is the opposite - if the Weight field in colINCOLIS is Text then you also need to ensure that the output of TextInput4_42 is rendered to Text, so
Set( PDD1; Substitute( Text( Value(TextInput4_42.Text); "[$-fr-FR]0.00" ); "."; "," ) )

and then your original code
Set( PDD1; If( CountRows(colNCOLIS) >= 1; First(colNCOLIS).Weight; Blank() ) )

The issue here is that a Variable needs to be set to the same data type everywhere you set it, so in the case, it would be Text.
