How do I refer to a G Folder using a variable? Should I put folder ID?
Yes, You need to use the folder id.
By the way, did you manage to get the comment form a task?
Unfortunately I did not see the log of your reply. Would it be possible to resend?
So there are two ways to do it. 1- Using Assign Task Email. You can respond to the task by replying to the email with the word Approved., Reject., etc. and any text you put after full stop “.” will be considered as comment.
The other way is to use Request Data action. It enables you to design a form and collect data from the user responding to the task using that form
