Help: Database search and results

I have created a database search and results set. Things seem to work fine until I add the join statements into the results page query string. If I don't use the joins , the search works great. It returns the correct results based on the criteria input. If I add the joins in, then basically all i get regardless of my search criteria is a complete dump of every listing. NOW - I don't expect any suggestions based on my above question, but was not sure if it was okay to post the code. Both pages total about 325 lines. If it's okay to post it I will. Thank you , Stuart
