The main part of this code works properly. It outputs everything correctly up until the point where I have to input ID's and get the output. It will only allow me to do it 2 - 3 times and then it just does nothing and I can't get it to output "Record not found" for incorrect ID's without either being in an infinite loop of "Record not found" or having it say Record not found 49 times (number of actual ID's it could be). I'm really stuck on this and have been at it for days! Please Help!
