Have a read of the reference pages for the functions that are causing you the errors and see if you can spot what you're doing wrong:

. . . and when you've read that, please read the posting guidelines at the top of this section of the forum.

PS you may also want to review some of the comparisons in your if() statements.

I don't know what language that is, but it is not C/C++.

Look at the examples and copy that syntax.
