code error on one page checkout

i have an urgent error to correct. preference will be given to anyone who can work on this as soon as possible. I have a pinnacle cart shopping cart - for some reason I am getting errors on the one page checkout pages only when using internet explorer - some people (especially outside the uk) don't get this error. the site is [login to view URL] Basically if you open I.E 7 and select a product and 'ad to cart' you'll get taken to the checkout page... when I click the 'checkout' button I get the 1st screenshot I have included , then if i click yes or no I get the second screenshot and then taken off of the site. So basically 1) I have non-secure items on the page after clicking 'checkout' (i am sure i have put SSL code on the https pages correctly) as the screenshot shows. 2) Need to find out why it isn't working. This happened previously and it was an error with the javascript library, but this is a different error. thanks ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
