I hope someone can help me with this ASAP!!

I am working with DW MX using the Insert Record feature. All of my form fields are named as well as my form, they hook to the database and each is configured properly. When I test my form online I get a 502 bad gateway error. I can view info from the database fine, just not insert. Any ideas???? It is Saturday and I am at work and would love to go home. IIS 5 running on win 2000 using ASP with Access. Thanks ahead of time. Rahel
