How to pass form value to hidden variable on same page

I have a html page with a form in it. The form prompts for a state code as well as other address information. I need to populate a second state code field with the entry first selected without prompting the user twice. How can I set the value of the hidden field to the value of the select form field?

Let me explain further, on the first line of code I get the state value from the user. I then need to use this same state value for the TaxJurisdiction variable without prompting the user for thsi a second time.

<INPUT class="textbox" type="TEXT" maxLength=2 name="Applicants.State" size=30>

<INPUT type="hidden" name="Applicants.TaxJurisdiction" value="<Applicants.State/>">

Can someone please explain how to do this?

You can do one thing, just call a function on entering value in the state field. may be on onchange or onblur. k. then in that function set the value of your second field to be the first one.

ie.
var first = document.forms[0].<first field>.value ;
document.forms[0].<second field>.value = 'first';

Yes, this works as I called a function from the onchange event.

Thanks for your reply!!!
