entering new info

I setup a loop to cycle through my database and pull up the requested information and store it in a variable name, and display it in a text box on the screen. My question is, when i edit the information and click submit how do i tell it to go back and see what the new information is? Becuase whats happening is its sending the information which is already in the variable back to the database and ignoring my changes. Do i need to create another loop to go back and search for the data that was entered into the text boxes? I'm kinda stumped on this one. Thanks.

Perhaps some type of loop so that I can go back and pull the information after it has been updated? Can I make the submit button do that? HELP!

Well I think there may have been a problem with my original code that was messing things up.. crisis possible averted
