Sorry for my ignorance. I did not understand nor i do not know how to add a response with a variable.
From what I understood, I initialized a Global Variable, Added a Notifier. Added a Call Notifier before and after Remove Item List. But no changes. Same error.
Disable remove list item block, and add a new label in your designer and set it to the responseContent variable.So you know what is being returned by google sheets, also try to put the link in a normal text string.
