I have a form that needs to check to see if a number a user enters is already used in a recordset. I have a script to run through the records and compare the number for a match but how can I get a popup message to appear when the script I am using to check the number is a server side script? Can I load the numbers from the recordset into an array and then use client script to check for a match? If so, how? Thanks for any help.
