Issue submitting forms



I have left my Web site out at my provider for a long while.
Yesterday I tried changing quite a few things on it but it all ended
in tears.

None of the form submit button submit anymore.

I am now wondering if the problem has to do with me using VS 2003
and .Net Framework v1.1 though I suspect that my provider has upgraded

I am copying below the snippet of View source differences between the
same 2 pages when running perfectly from my environment and not
submitting at all from my ISP.

If anybody has any idea as to what the problem is and how to solve it,
all suggestions very welcomed.

---Code that works-------
<form name="form" method="post" action="Cart.aspx"
language="javascript" onsubmit="ValidatorOnSubmit();" id="form">

---Code that doesn't-------
<form name="form" method="post" action="Cart.aspx?
action=addSKU&amp;SKUID=JBT01133UKWHM" language="javascript"
onsubmit="if (!ValidatorOnSubmit()) return false;" id="form">

I do not understand why the Action is not the same.
..... and especially why the onsubmit changes from one to the other. I
suspect that this is the problem.
