It's very simple if you are not a lazy reject who doesn't know how to think. Oh sorry that was rude...
If you need this to work without the message:
document.location.href = document.location.href + document.forms.hiddenFieldIputMyPostVarsInInQueryStringFormat.value;
If you are to lazy to make a hidden field and set it's value .... what exactly are you being paid for again Oh wait was it to write code or maybe program Nah they pay you to sit on youe @$$ and complain about having to write at most what 6 lines of code..
Mommy I'm stupid and it's Microsofts fault!
