Aaron,
It seems like what you really want is an array of data. If you have your 
form submit the individual fairs as elements of an array ($fairs), 
you'll find php's array functions very helpful when determining what 
indeces are set. It seems that your prepending an integer to the string 
'fair_name' is just a poor man's array which makes your looping tests 
akward.

Best,
Robert Redcay
