Details button does not show detail

I just installed nop commerce at www.corei5.com.au and added few products.
But when I click the details button in each product it does not show anything .

Do you know what I am  doing wrong ?

Is there any error records in the system log? (System Log: Admin Area/System/Log)

There is nothing under System-> Log - only some old errors.

i checked your website,

Details Buttons is working fine for one product "RP-SMA 2.4G 17 dbi Wireless Antenna Booster + Base "
and not working for other 2 products

I guess delete those 2 products for which "Details" button is not working and create new products with details and see if it's still working or not OR add 2 more products with same name and see if it works for newly added products or not.

I think I found where the problem is.
Under ManageProduct - Edit - Product Template -> select "Single Product Variant."
