SELECT and Radio Box

[eluser]cidevelopment[/eluser]
Hello Community,

In the edit form I want to set the posted value (which user has changed in the select and radio box) in a select box and radio group when the form validation error occurs and the page is again displayed.

I am using

Code:

set_select('fieldname', 'value')

but i am also loading values of select box and check box set to the ones which are in the database when the form again gets displayed after form validation.
