You are doing
and apparently you think that the name
musimw is some global.
Yes, it is, in MSIE.
But not in standard JavaScript.
You must use "scope" to find it. To wit:
Code:
document.musimw.submit();
or
Code:
document.forms["musimw"].submit();
or even
Code:
document.forms[0].submit();
However...
You declared your page to be xhtml1-transitional.dtd, and in xhtml, <form> names are deprecated. So, technically, you should change to using
Code:
<form id="musimw" ...>
and then do
Code:
document.getElementById("musimw").submit();
though the code
Code:
document.forms[0].submit();
is correct so long as you know that the <form> in question is the only (or at least first) form on the page.
