expected unqualified-id before numeric constant In function 'void Scan()'

This about says it all. I am new to the Arduino and New to the C language. But, I have written may other programs in other languages. I was trying to add some subroutines written in Pbasic on the BasicStampII to the LARS program when I got this message.

Any ideas??? :-?

Post the code and we'll take a look-see.

OK, here is the code:

I think this should've been in the Syntax part of the board. Sorry :-[

I moved as much as I could to the Syntax part of the board. Follow me over there, please.

Thanks!
