VBA Function Help

Hi,

I'm trying to simplify some of my VBA function codes. For example:

Function func1(x,y)

zzz = x + y

func1 = zzz * 2

End Function

Function func2(x,y)

zzz = x+y

func2 = zzz * 3

End Function

Is it possible to not keep typing in the "zzz = x+y" line in each function that needs the "zzz" value?

Thanks,

Jay
