Hello all Power Apps experts,
Here I have a new problem.
My homepage in Power Apps is a gallery data table with items information and there's a bottom called copy this item.


With clicking this bottom, I hope the user could skip to a new screen with the item he chose. In this new screen, he can change any information he wants to change and by clicking the submit bottom, he will skip to successful screen and a new item will be created in the gallery data table.

So for the "copy this item" bottom in p2, I just use the function navigate in on select session.
For the "submit" bottom in p3, I use the function in on select:
Patch(Sharepoint data source, Defaults(Sharepoint data source),FormCopy.Updates);
SubmitForm(FormCopy);
Navigate(ScreenSuccess));
However, it could not jump to the success screen and could not submit at all.
Anything wrong with my function or is there any advice?
Thanks!
Regards,
Yiqian
