Thanks for the replies.
It took a lot of trial and error but i got it...finally - angle(X2_135.X, X2_135.Y, LayoutWidth/2, LayoutHeight/2)
Although i read posts, tutorials, watch videos, it takes me a bit of time to comprehend things. That's just how my brain works. Sorry i'm not as quick as some of you guys.
Again, thanks for the help. Very much appreciated.
