I have a rotating ad banner system that randomizes the ID for each refresh of the page... It takes a range of numbers, and selects a random number, between 1 and the maximum recordcount. The only problem is that if records are deleted, it includes that ID in the range.
How can I randomize within a set number of EXISTING records?
What will happen, is that it will randomize between 1 and 33... Eventually, it will try to display the banner with the ID of 10... However there is no banner there with that ID... How can I avoid this?
