A problem where all but one MySQL column echo's out

I have a column in a MySQL table called 'set0' which contains the single digit '1'.

When I try and echo it via $row['set0'], '1' doesn't come through, yet every other column in the table does I echo does come through.

Does anyone know what could be causing this to happen?

Never mind, it was echoing but I just couldn't see it as it was on a background. I'm cooked and calling it a night. Thanks for taking the time to read my pointless thread.
