	formula: If left({city_field},4) ="city" then right({city_field},len({city_field})-5) else {city_field} Not tested, but should work.

	I always thought you had to have a length with the mid statement (or is that just for old BASIC code).

	I know length is optional in Crystal, in fact the only thing I know of where you need to declare the length/number of characters for mid is Excel, and even then you can get round it by entering a high amount of characters - eg =mid(a1,3,9999).

	even old BASIC, you just needed the starting point...at least from vb3 or so on....maybe even QB4 .Net is the same way...if you don't specify length, it is everything from the start to the end of the string. TSQL wants a length, but you use the same trick the rkrowland said...just put in a large value.

	When I mean old BASIC, I am talking Apple II, Commodore 64 days. :-)
