I am not sure I got this error every time I open edit the application. The red line error showed Incompatible type.

All I did now, I comment out the red lines and un-comments. Then, red line will go away. Until next time I open the application, any idea?

@usaman45 ,

This occurs because you are storing values into a variable with different data types. For example you could be defining a variable as a text data type in one area of the application, and then defining the variable as a number type somewhere else in your app.

It can be quite cumbersome to identify which variable is causing the problem. Here some checks you can do:

If the error is occurring on a Form and a Gallery, check the data source of the Form and the Gallery are the same
Check you do not have a Global Variable and a Collection with the same name
Check the Variables section and see if any Variables are returning “error”. This view is essential because if you click into the record, you can view how and where the variable is being defined.

To identify which variable definition is causing the error, you can do this by process of elimination - delete each instance where the variable is being defined and then see if the error still appears.
Careful with your formats when applying the Format function to a variable. For example, if you're going to wrap a variable around with a Format function, ensure this is also the case elsewhere in the app wherever this variable is also being defined.
Although you may think you fixed the problem because the error is not appearing anymore after you made a change, restart the app to check if the app still works. This is because the problem may arise again on a restart

Thanks for the suggestions but I am still not able to fix the issue.
I check Variables and there is no error and just show No value.

As mentioned, a simple solution is delete one of the variables, save and then restart the app. Then check if the error occurs. Keep repeating this until you can pinpoint which variable is causing the error.
