Dynamic Text box

Why oh why does this not work???

I just want the dynamic text box to have a number start at 0 and go up 1 every time you click on the score box..

thanks people much apreiciated :D

On the first frame add the following:
_root.score = 0;
Thenselect your dynamic text box and in the Var field put _root.score
just tried it and it works great after you make those changes.
