The bit in bold has me stumped, mainly the “with” part… I knew the rest in reference to my player movieclip. It does something though because if i remove it the code breaks. It’s for a college project and my lecturer won’t accept my code until i know what “with” does… It also seems to cause an error when the player hits the end zone(goldapple).

This the error in the output box  
**Error: A ‘with’ action failed because the specified object did not exist.**

So anyway what does with do… and is there away to remove it without breaking my code?

Thanks in advance.
