Based on the coloring of the text, it appears that you somehow have bad characters in the first line. You should delete it and retype it.

Note by the way that you do not have any if statements in the code you show. Your code is not doing anything conditionally. In the code you posted, x>0 is just a computation whose result is to be displayed.
