how can i change this query

[olm75]

i think my problem mostly lies in the query itself...this is what i have:

[!--PHP-Head--][div class=\'phptop\']PHP[/div][div class=\'phpmain\'][!--PHP-EHead--]

SELECT venuename, address, city, `state`, zip, phone, areacode

FROM venues_new

WHERE venuename LIKE \'MMColParam%\' AND areacode = \'varAC\'  

[/span][!--PHP-Foot--][/div][!--PHP-EFoot--]

 

 

but what i want to do is allow the viewer to search with 1 or any combination of fields in the search form...to get results or narrow results, what this query is doing is making them choose both fields without having the option to choose just one...if they want a much broader search....and i have 4 more list/menu search fields to add on....

here is the form:
