Setting Worldpay integration live

Just being cautiuos on this one as I have previously had a techie to do integrations.

Got the the final hurdle with Worldpay integration and recied the following instructions

"To start accepting live transactions using the WorldPay Payment Gateway, you will need to change your website to run in LIVE mode.

To do this, either:
- Remove the testMode variable from your Purchase Token code
or
- Change the testMode value to 0 (zero).

For example:
<input type=hidden name="testMode" value="100">
to
<input type=hidden name="testMode" value="0">

And ensure that <form action> URL is set to "https://secure.worldpay.com/wcc/purchase"
For example:
<form action="https://secure-test.worldpay.com/wcc/purchase" method=POST>
to
<form action="https://secure.worldpay.com/wcc/purchase" method=POST>
"

Is this achieved by seting test mode to off in the Worldpay Payment Extension?

Thanks anyone.

OK so I just selected to switch it off and test with a live card.

Worldpay recorded the transaction and sent e-mail confirmation but there is absolutely nothing in my shopping cart, just like it warns in the User Manual.

Anyone know the wonders of Worldpay for Open Cart?

Thanks

Check this thread:

tho you should be ok if using 1.5.1.3 already

Looks like it was password match.

WP disguises the digit count in their interface so the only way to check is to re-enter password.

Thanks
