Can anyone suggest whey I dont get any results with this search?

SQL reads:

SELECT SupplierName, Location, ShortDescription
FROM Query1
WHERE 'TimberSpecies' LIKE MMColParam AND 'CategoryTable' LIKE MMColParam2 AND 'Location' LIKE MMColParam3

MMColParam 1 Request.Form("keywordSearch"
MMColParam2 2 Request.Form("location"
MMColParam3 3 Request.Form("category"

Mally.
