Enable/Disable Button through javascript [modified]

[xfitr2]

I have a asp.net page where my button is enabled or disabled depending on whether two textboxes are properly filled out. I enable/disable the button through the onchange events of the textboxes. Once button is enabled and I click it, the postback seems to have disappeared because it does nothing. I enable/disable the button like this:

	function checkBuild() {
		document.getElementById('sMsg').innerHTML = '';
		checkBAL();
		checkINI();
		if ((checkBAL()) && (checkINI())) {
			**document.form1.btn1.disabled = false;**
			checkWarning();
		} else {
			**document.form1.btn1.disabled = true;**
		}
	}

I've read that in order for the button "btn1" to postback, I must have it enabled onLoad which I have done for testing. Therefore, if I click the button before my javascript fires, it works; only stops working once my checkBuild() function is called by the textboxes javascript onchange event. Can anyone help with this issue? Many thanks.

Call the javascript function on the bottom of the page.
