I expect that you read the datasheet for your processor just as carefully as you read the posting instructions for posting source code.
And I expect that you wrote your source code just as carefully as you wrote your source code comments.
When reading the compiler manual and getting started manual, did you intentionally decide that bit variables where useless or didn't you notice them?
And how did you verify that it isn't an output problem but instead an input problem? And how did you verify if any processor pins have an alternative function that may interferes with your intended use?
