Checkout page dissapears when pop up activated

[quattro]

I have an issue with our checkout section.
At the point where the customer chooses method of payment, we have an image that can be clicked on to open a pop up with information on how to apply for finance. When this happens and the window opens the checkout page dissappears and reverts back to the catalog home page. We need to have the checkout page in the background so that the order value can be entered into the finance application form. - Any suggestions welcome.
Many thanks

What is the format of the URL for your pop-up page?

I have contacted our site builder and the URL is http://www.furnituretoday.co.uk/credit.html and thit is using a standard macromedia 'pop up window' behaviour.
Hope this helps

Try using a link of the following form:


<a href="JavaScript:ShowPopUp('http://www.furnituretoday.co.uk/acatalog/credit.html',550,500)">Click here</a>


... as this uses the Actinic popup code rather than custom code, which may be causing a conflict.
