The error message means that the variable "vecy1" don't exist when referenced in 
the #if statement.
Make sure that every variable have been properly declared, with the same 
capitalisation, before the #if statement. make sure that the actual declaration 
cone was effectively parsed before the #if is encountered: any other #if before 
it? Are they properly terminated with the coresponding #end?
Any complex #declare? Are they properly closed with all required closing braces "}"?
It can be declared with #declare or #local. If using #local, is the deffinition 
still in scope?
A beter way to code your test is #if(vecy1 >= veca) shorter, faster to parse and 
easier to read.

By the way, it's strongly recomended to ALWAYS start user deffined variable by a 
CAPITAL leter to help prevent any eventual name clash. Keywords are all lower 
case, as are all built in variables. All lower case = reserved items, mixed case 
= user deffined.
