this should be researched in the javascript archives:

google -> groups -> javascript

this is probably what you want

var mytest = document.myform.myfield.value;

if( mytest.toString() == "" )
        alert( "No text in " + document.myform.myfield.name );

but i would suggest getting on that group..they are more experienced
with javascript...
