Invalid value for field, expected a string

[FelipeCaru]

Hello all,

I have a problem with my app now. In my Excel sheet I have a column called 'Completado' which has either 0 or 1, and the column is formatted as 'text'. In PowerApps, in an editform I have the formula:

If(DataCardValue28.Value=true,Text(1),Text(0))

And also tried variants with "1" and "0".

When I go to save the form, I have on the SubmitForm(form_ELT); the error, where the error says:
The requested operation is invalid. Server response: invalid value '0' for field 'Completado', expected a string.

I am having troubles with this since I already have the column in the Excel Sheet as text field, and the value of the card on the 'update' property has the formula shown above, which should make it text/string, yet, still have this error.

What can I do?

Hi @FelipeCaru ,

What is the control type of DataCardValue28? Is it a toggle control?

Please try below formula instead:

If(DataCardValue28.Value=true,"1","0")

Regards,

Mona

I did had that tried but didn't work.

However, I just noticed why nothing worked: originally, when the form was made, the column was in number format, thus, the card had number format. Now much later the source has it as text, but the form still had it as number, therefore the problem. I re-did the card and used the formula, and then all worked good.

it's weird - I just got that error and I'm sure that I hadn't changed the data type, but the excel column had changed from number to general. Changed it back and works ok again.
