Hi All,

 I developed a new Workflow with new screen all are new fields and i want to customize a search form to use it .

the probelm is i want the user to write one field say IP and search with this value in  three DB fields.


1-  User Open search form.

2- Write IP in Field .

3- Sm search for this Value in Three fileds .

is it applicable as you i know that in search form each filed in the form realted to only one field in DB.
