Well, since the punctuation was non-existent, maybe you need to parse the verbage

you mite change your mind if you had one

as

You, mite, change your mind, if you had one.

But even then, if you don't currently have a mind [to do or not do anything] to change, it might be difficult. That's because "if you had one" implies that you might have lost your mind.

Yup! I'm there...
