Error Code: HTTP method GET is not supported by this URL

Hey,
I need some help with some javascript code. The code works fine in HTML editor but produces this error, "HTTP method GET is not supported by this URL" in WordPress.


Problem: I can't get this URL: https://www.geonlineapply.com/servlet/MCSGenericApp to function probably in WordPress. Any suggestions would be highly appreciated!


Here's the HTML code:


<SCRIPT language=javascript>function callSubmit()


{


document.frmApplicationTermsCond.submit();


}


</SCRIPT>

<FORM name=frmApplicationTermsCond action=https://www.geonlineapply.com/servlet/MCSGenericApp method=post target="_blank">
<INPUT type=hidden value=N name=MCSCLIENTTEST> <INPUT type=hidden value=OR name=PRODUCTCODE> <INPUT type=hidden value=03 name=GROUPCODE> <INPUT type=hidden value=1290800802 name=MERCHANTNUMBER>
