Just sat down and had a look at it.

How do you actually mean to do it with: search.cgi?query=&Otherfield=something
Do you mean to add that string on to the form action statment? But I have 5 custom fields, each with severl options. So do I need to add in =&otherfield for each field I have? Are they not added on to the queary when selected in form?

IE if someone selects from a dropdown menu the colour: white
And from a second drop down box they select: yes
Would this be added on automatically to the search.cgi? string??

Just not sure how that works and what exactly you mean by it.. Hopefully I can work it out with some help! Would improve the search function a lot if you can actually narrow down searches with dropdown options.

Thanks again!
