GDD System Error

[Dinodin]

I'm trying to add the GDD system into my map but when I'm trying to save my map I keep getting this error and I dunno how to solve it or what it means.

It means there was an error with the variable GDD_Event. Make sure the variable exists and is a real variable.

Thanks. I had to make it a REAL variable and now it works!
