Sorry, Nitro, I completely overlooked this post 
It turns out you cannot use ":" after then if you want a block-sentence if. The syntax was changed on 1.6.x
":" Colon after then means you have to finish the IF in the same line like in traditional BASIC (so remove it there to allow the program to compile)
