I use the data pull data formula, but the problem is that when I try to modify the data that I obtained the , the modifications and the form are not saved
Welcome to the community, @alkhuttab! You can only edit your question (that has the pull data formula) by removing the pull data syntax from it. I hope this is what you are trying to do.
Can once() not be combined with pulldata?
At least, a calculate with pulldata might be used and then referenced with once()?
