I can’t join ACM

So, as a part time postgraduate student I decided it was time to join the ACM. I’ve been trying all of this week, and I still get this error message on the sign up form:

    Error Diagnostic Information
    
    QUERY
    
    The QUERY attribute of the tag does not specify the name of an available query
    
    The error occurred while processing an element with a general identifier of (CFSELECT), occupying
    document position (871:10) to (871:90) in the template file
    F:\INETPUB\WWWROOT\PUBLIC\QUICKJOIN\QJ_PERSONAL_INFO.CFM.

    Remote Address: 203.17.68.254
    Query String: form_type=Student/
    

I tried emailing the address in the error message, with no luck. Does anyone out there know someone from the ACM who can get this fixed so I can join?
