I have a databse which links locations to regions of the UK
and also to a type. They type and the regions are stored in two
separate tables both of the type with two fields id and text. The
ids link to another table (location) which has a regionid and
typeid field to refere to the detail tables. I have a search page
to allow to search Region AND Type which works fine if I select
something in both text boxes but returns nothing if one is left
blank. How do I get round this?
