Tim, below are two scraps of code

[GriffMG]

Tim,
below are two scraps of code for a button.
With javascript (I've assumed you mean javascript for the client side) you must watch the case v. carefully.

This bit is the code to execute
[tt]
<SCRIPT LANGUAGE=&quot;JavaScript&quot;>

function java_close_window(){
window.close();
}

</SCRIPT>
[/tt]
this defines the button
[tt]
<input type=&quot;button&quot; value=&quot;Yes&quot; onClick=&quot;java_close_window();&quot;>
[/tt]

Does this help?
