Where did you specify the unit "u"? I can't see it anywhere, can you?

 

[AceLegend90]

You forget that locals are only exclusive to the function they are in. In this case, your "u" variable does not exist since it has not actually been declared in that function. Add a "local unit u = GetTriggerUnit()" line at the top of that function.

thnx a lot guys

 

[waaaks!]

use triggering unit instead of U, or use globals for it
