Hi Constructors , I got a problem about Variable .

I want to compare like ScrollXLeft and a number ,or ScrollXLeft and ScrollYLeft

If ScrollXLeft = 0 then ......

Or

If ScrollXLeft > ScrollYLeft then.....

I found the solution :

add variable : Panleft = 0

Set value ; Panleft = (any system variable)

then using system----Compare value
