I try use Array to recording the position of mouse at every times press.
But i don't know how could get a index to write array elements. I use a Text box and i set the type be Number. Hope i can get the number as Array's index. But it's always said "this parameter requires a number, not a string"!! I know it's need a int or something. but there is no integer or another type. Someone help me? for this stupid problem...
