Thanks for this really useful website.
I have used your Regex Tester quite a lot, especially the VBScript client-side version.
Unfortunately it seems to me that the tool is not working anymore, perhaps from the last update a couple of months ago.
It looks like the following block is to blame:
<select name="..." id="..." onchange="checkEngine(this.form)">
When executing checkEngine(this.form) the following error is thrown up: Object expected.
Exactly the same error is risen a couple of lines below the previous ones:
<input id="btnExecuteClient" onclick="execute(this.form)" type="button" value="Execute" />
I hope this will help to fix the error an bring new life to this essential tool you have built.
Thank you very much.
