Calling url from a form - err using ".value" method

Question

I'm trying to call url from a form, which seems to be the subject of many of these Posts.
I have a form with a combo box/LOV and a button. The LOV will read a url into the combo box from a table of url's.
I used the following code in the "OnClick" Java Script Event Handler section, which I pieced together from other posts in this and other forums. (i.e. I'm a pl/sql programmer trying to use Java Scripts for the first time).
OnClick
var X = FORM_DRWING.DEFAULT.A_DRILLDOWN_PATH.value;
run_form(x);
When I attempt to run this form from the "manage" window, I get a run time error "FORM_DRWING is undefined" upon clicking the button. FORM_DRWING "IS" the name of the form!
The runform() function in the "before displying form" pl/sql code section is
htp.p('<script language="JavaScript1.3">
< !--
function runForm(v_link)
window.open(V_LINK);
//-->
</script>');
This code was from yet another Post.
Any help would be appreciated.
Thanks, Larry

Hi Larry,
the problem could be that you need to preface your form with 'document.'.
i.e.
var X = document.FORM_DRWING.DEFAULT.A_DRILLDOWN_PATH.value;
