It seems that for any product I add a variant to when the Options button is clicked an error "Object reference not set to an instance of an object" occurs instead of displaying the detail page. I am running the newest version of the shopping cart with DNN 5

When you click the options button is it from the buynow module or the featured products module?

From the BuyNow module. Using the links attached to the product name and icon work, but the Options button causes the error.

I cant replicate the issue. Can you post a screen shot of your product variants and product detail settings from the cart admin. In the dnn event viewer is it saying that the error is on the productlist page or the productdetail page?

Ok so it says the error is on the productlist page. Can you confirm that you are running cart version 2.90? Also, since its not happening on my test system I need the following so i can setup the exact settings that you have:
- Post a screen shot of your product variants from the product setup screen
- Post a screen shot of your product detail settings from the cart admin settings

I'm wondering if this has anything to do with the problem. The version I originally downloaded and installed upon purchase was 2.85. I was provided (on 5/25/10) with the link to versioin 2.89 which I installed in order to fix an issue with the Bill Me Later option. The variants I entered did work at least once upon original creation. I not exactly sure when they went off-line, but I seems it may have been after the update.

Thats possible you might want to try upgrading to the latest version 2.90 can be downloaded from the downloads page. Or try installing 2.9 on a new dnn install and see if you still get the error with a fresh install that will tell you if the issue accurred after the upgrade.

I thouht this was fixed yesterday. I added another item to the group and got a new error when selecting one of the variants from a dropdown.
An error has occurred.

Can you make sure that all your sort orders are filled in and unique for the variants.

Can you post a screen shot of your payment detail page settings from the cart admin settings.
At your service,
