Increasing Global Variables

Hey, I was wondering how I increase a global variable by 1.10 * itself, whenever I try I get told that the * is in the wrong place.

Thanks in advance!

should just be

GlobalVariable = GlobalVariable*1.10

but the other way around should work.. are you sure your GlobalVariable is a number and not a string?

Of course, i forgot to put the name of variable again. I was just putting * 1.10 no wonder it was working, thanks!

Or use the add action and global * 0.1
