As you haven't shown the code that produces the error when it's compiled, I can't say for sure what the problem is. However, here are links to three instances of the same error:
• error: expected unqualified-id before 'if' error: expected unqualified-id before 'if' on stackoverflow
• Arduino: error: expected unqualified-id before 'if' (using ping sensor) Arduino: error: expected unqualified-id before 'if' (using ping sensor) , also on stackoverflow
• error: expected unqualified-id before 'if' on arduino.cc.
In each case, the problem was due to executable code (as opposed to declarations) appearing outside of a function. You may have put some executable statements outside of loop() or setup(), etc.
