Using VB code with PHP Session Variable

[BadChough]

I have successfully used the following snippet of code to launch printers on a php webpage, and to close the page when the printing is done.

<object id=WBControl width=0 height=0 classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2></object>
<script language=VBScript><!-- //
Sub VBPrint() On Error Resume Next
WBControl.ExecWB 6,1
End Sub
//--></script>

<script language=JavaScript><!-- //
if (window.print) self.print();
else if (navigator.appName.indexOf('Microsoft') !=-1) VBPrint()
setTimeout('self.close()',3000);
//--></script>

However, when I add a php Session Variable at the start of the page the printer will still launch when requested, but the page fails to self-close.
I there a way around this problem?

Please ignore the drivel above.
I don't understand what was going wrong, but it's sorted now.
Sorry.
