First, you don't want to put quotes around variables or operators (or both), it creates a literal string which will not be evaluated as code.

Then, you will want to test the variables using their names (a and b), instead of the values they contain.

I already tried it with the letters and without the quotes, but still having trouble. I cannot get past this to complete my tracker. Thanks for your input.

There should also not be a semicolon between the conditional clause and the brace that starts the following code block.
