We manage an online directory and we are thinking of displaying banners based on keywords that users search for in our site's search field. Basically if a keyword exists in a user's search string, then a particular banner will be displayed. We've considered using site variable as an option but its not clear what to enter in the Names and Values field. Is using Site Variable a good way to do this and if it is, any suggestions on modifications we would need to make to the code, etc. Thanks,
