[goh]

I was creating a solid bubble item (You know, from Mario Advance). But the error has occured!
Check here:

Code:

ERROR!!! :: ############################################################################################
FATAL ERROR in
action number 1
of Draw Event
for object obj_solidbubble:


Variable obj_solidbubble.item(100225, -2147483648) not set before reading it.

--------------------------------------------------------------------------------------------
stack frame is

Can anyone help me on this please?
