asp ajax code

this shd be easy for an ajax guru. we have a working insert record and edit record asp script. see [login to view URL] [add record] and [login to view URL] [edit record] What I want done in line 602 in [login to view URL] is when a user selects male only the male related dropdowns appear i.e. Mens Short Sleeve Shirt Size to Mens Jacket Size and for female only Ladies Short Sleeve Shirt Size to Ladies Jacket Size and for [login to view URL] [edit record] similiar structure, if whois recordset is female only display the female dropdowns and same for male.
