Page Not Found?

[LeonardBanks]

Hello all.

I am having an issue with a page that contains a form. The form submits to itself.

The button used to submit the form is a <button..> with an onclick that validates some data then does a document.frm1.submit(); if all data checks out.

I have these headers set:
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
Header('Pragma: no-cache');

My issue is that sometimes, and I cannot recreate regulary, after clicking the button I get a "Page Cannot Be Displayed" error. I click the browser's back button, and all form data is gone, I hit the button and again "Page Cannot Be Displayed". I can hit back and then the button over and over with same "Page Cannot Be Displayed". Now when on the "Page Cannot Be Displayed" if I refresh it first asks if I want to resubmit data, I click yes and the page will load but the data submitted is not there. NOW if I hit back and then hit the button it will submit just fine. The refresh is needed to fix the issue. I have not found a pattern that will cause the "Page Cannot Be Displayed" error.

Any help would be greatly appreciated.

How exactly are you doing this? Javascript runs on the client while php on the server. You'll need to post your code.

The button has an onclick event that uses javascript to make sure certain fields are completed. If they are completed then submits.

<input onClick="return ButtonSubmit( 'Stay' )" type="button" value="Save">

function ButtonSubmit( StayOrReturn )
{
ret = true ;
if (eval(frm1.days_complete.value)==0 || frm1.days_complete.value=="")
ret = false ;
if( ret != false )
{
alert( "Saving this Cost Breakdown Sheet does NOT submit." )
document.frm1.savecbs.value="Save CBS"
document.frm1.float_submit.value="Save CBS"
document.frm1.Stay_Or_Return.value=StayOrReturn
document.frm1.submit();
}
else
{
return false;
}
}

I normally HATE bumping. But I am in a little crunch. Anyone have any ideas?
