Imacros help needed

Hi guys!
I am pretty new to all this stuff and found the imacro extension by a recommendation from a user on a previous thread I posted.
I recorded my macro and I can loop it thru the play function buy I need to have the component that is filled be different every loop
I am pasting the macro code below so it should be much clearer

VERSION BUILD=1011 RECORDER=CR
URL GOTO=https://xxxxx/admin/plans/edit/2
TAG POS=1 TYPE=TEXTAREA FORM=ACTION:https://xxxxxx/admin/plans/edit/2 ATTR=ID:i_coupons CONTENT=test1
TAG POS=1 TYPE=BUTTON FORM=ACTION:https://xxxxx/admin/plans/edit/2 ATTR=NAME:submit

I basically want the content value to increase by one every loop , so instead of having test1, the next loop should enter it as test2 , then test3 up until test 5000.

Thank you very much for your help!

Anyone? Please

Try something like this perhaps?

What you are looking for is a loop. Seems like that tool uses !LOOP to define a loop.

these are much easier with js nevertheless lol.

It’s been years since I fiddled with iMacros but you should be able to do that by setting a variable (https://wiki.imacros.net/SET) and then incrementing it (https://wiki.imacros.net/ADD) in your loop.
