I need some help

Ok i want to make it so you can slelct a bunch of units and make those units a unitgroup, and when you press "1" it will do an ability to all of the selected units. Also when you unselect them, it takes them out of the unit group. I would like it to do the whole caster to target art thing like on health steal. And things like areial shakels to 5 people and they all become immobile and take damage, and arent invulrn.

You will probably get much better response if you actually try to do what you want, fail, think some more, fail again, post your code with an explanation of how you think the code should have worked, and how it actually worked.

Why will you get better response then, you wonder... well, it shows that you have given it some thoughts, and it is much easier to help you getting it right if we know how you are thinking.
