You donā€™ say what happened. Did it work?

prg iā€™m desperate, it doesnā€™t work, iā€™d rather do it with hooks but i canā€™t in any way

Iā€™ve seen your other posts, and there is a reason why youā€™re not getting answersā€¦ your posts are incomplete, you donā€™t give sufficient information, and when people ask for it (see above) you still donā€™t add anything relevantā€¦

Please see this topic:
