HELP! RENT ITEM THAT CHANGES GROUP ID THEN TURNS BACK TO PREVIOUS GROUP ID WHEN EXPIRES

[SorryV2]

Can someone help me with an item script that changes the group id then turns back to previous id when expired?

So I have this certain item for example a certificate that can use @autoloot (modified groupid) when used then goes back to (groupid 0)

when it expired.
 

This is my item script. LoL IDK if I'm doing it right.
"{if (groupid==0) changegroupid (groupid==7);rentitem 32004,2592000},{},{}"
 

A help will be so much appreciated. Thank you in advance.

PS.
I had enabled VIP system but
Its a separate function from what I'm doing.

It's like a different system from VIP to F2P. you get what I mean? xD Sorry though I can't elaborate.
