yes i inderstand that, but you can create a list of (all?) possible comments, that would restrict them from entering just anything. for instance, what if, instead of...
I Called the customer and there was no reply,,,,the tech entered
I Called the customer and there was no answer
I Called the customer and there was no response
I Called the customer and there was no 1 home
I Called the customer and there was no one at home

these are all the same entry, but trying to do a search that would return a "true" in each case would be next to impossible. however, if the tech was only allowed to enter "I Called the customer and there was no reply" then a seach on that is fairly simple. see what im saying?
