So I'm working on a search sql program, I want to add a message that pops up in the userpane for if there are no results found. I know how to do this for an if/else statement, but I had to change my 'if' to 'while' to run the loop. Can I still add a message into a while loop?



This is what I had, how would I tailor something like this to fit the program?

Please explain what that means.

My favorite is a chocolate cupcake with white frosting and tiny ad sprinkles.
