code check please

Hi

have a mysql databse which includes colums: UserSex, UserEthnicity,UserAge, UserArea etc.

I've created a form using spry select to search the database for any combination or age, sex ethnicity etc.

When I add four test records to the database and then run the search page in the drop down box  I see (for example) Male female,male female so it's listing the entry for every record.

A google search told me that in the record set I had to use SELECT DISTINCT

so I edited the record set as below

SELECT UserEthnicity, UserAge, UserTypes, UserArea
FROM users

But this hasn't stopped the duplicates.

Is this coding correct?

thanks

Ian
