Hmmm, not exactly sure as to what you mean. Try something like this:

Code

checkOne = checkName(characterName())  # Include the brackets!!

I don't think that this is it...
(pretty sure characterName would be a variable; even though PEP standards dictate that variables_should_be_underscore_seperated and functionNamesShouldBeCamelCase)

Whole code would be required to see what you have done wrong; I think it might be that the checks are being run, and return a None value, so that nothing is passed into the next function?
