jquery submit one form when page has more than one form -

i have page 2 forms. id="form2" , id="form3".

form3 within form2. inside form3, there button jquery action submit form3 when click on it, nothing happens.

this written in classic asp , jquery.

this form2

<form id="form2" name="form2" method="post" action="process/processeditjob.asp"> 

and within this, there following form:

<form id="form3" method="post" enctype="multipart/form-data" action="uploadscript1.asp"> <input type="file" size="40" name="file1"><br /> <input id="goupload" type=submit value="upload!"> </form> 

the jquery linked button follows:

    $('#goupload').on("click", function(e) {     e.preventdefault();     alert("entered");     $('#form3').attr('action', "uploadscript1.asp").submit();     }); 

when click on button, can see alert message saying entered.

if move form3 new page, works perfectly.

i not sure why not submitting within first form.

thanks saj
