Error Variable set (incompatible with the types of values in other places in your app)

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,

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.

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.

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.

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 ) )
