_doClick Function - please help

I know that domino biult in a function called _doClick called on submit or on change value in a listbox field but in my form this function return error “Object doesn’t support this property or method” at the line form.submit();

this is all the code created ( i think ) by domino, which is my mistake??

function _doClick(v, o, t, h)

{

var form = document._webCorso;

if (form.onsubmit)

{

 var retVal = form.onsubmit();

 if (typeof retVal == "boolean" && retVal == false)

   return false;

}

var target = document._domino_target;

if (o.href != null)

{

if (o.target != null)

   target = o.target;

}

else

{

if (t != null)

  target = t;

}

form.target = target;

form.__Click.value = v;

if (h != null)

form.action += h;

form.submit();

return false;

}

Have you tried using a debugger (there’s either one built into your browser or available as an extension/add-on) to see what the entity named “form” is?
