In response to mails and replies:

thankyou for your interest in my woes.

code and error messages are included. the errors are generated when I add
'char name[]' to the customer header in the protected section. sorry if this
seems like loads but i'm not sure where the problem is coming from. Like I
said, its fine without the 'name' declaration,

When I said deleting all the files I just meant my code files, and replacing
them. Sorry for not being more specific.

Please don't laugh at my code. I'm fairly new to this and attempting a big
project. All Im trying to do at the moment though is set up an array of
customers who have names and numbers. How hard can this be? Obviously harder
than i thought!


thanks again

joanna
