I have seen this question but my question is different. My sheet uses comma as decimal separator but when I publish it as a form, dot is used as the decimal separator.
How do I change decimal separator in a form based on a Google Sheet?
When viewing/editing the form I have looked under the ⚙️- and ⋮-menus but couldn't find anything that looked applicable there.
Interesting tidbit: I have enabled response validation in the form as well as data validation in the actual sheet. The condition is a value between 1,0 and 2,0 - but in the form these values aren't accepted, instead I have to enter 1.0 and 2.0 as limits.
If I enter 1,5 in the form it is rejected, I have to enter 1.5. But when I look in the sheet, 1.5 is rejected - I have to change it to 1,5 for it to be accepted.
