Can anyone tell me what I am doing wrong? I can't get it to calculate the charges.

Can anyone tell me what I am doing wrong? I can't get it to calculate the charges.

what you're doing wrong?
you didn't paste your code in your post

well, maybe he has nothing to post, in which case there's nothing to do the calculation :)

just a suggestion: use code tags and indentations. might make us actually willing to read the above code.
as far as I can tell, your code is doing exactly what you programmed it to do.
doubt a lot of parking attendants will use it, though, same cost to park for one hour as for parking for a hundred hours? hehe :)
