eCart5 - "Add To Cart" button setup

Hi.
After finishing my database,now I am trying to add the "Add To Cart button" for each product in my webpage.
I inserted 4 buttons in my webpage and then when I click on the buttons these problems happen:

Problem no 1:
I do not see 4 of my 6 column from database. I see only ProductName and ProductSKU.

This is the structure of my database:
ProductID, ProductSKU, ProductName, ProductCategoryID, ProductPrice, ProductThumb.

Problem no 2:
When I click on all 4 "Add to Cart" buttons (e.g. simulation for buying 4 different product), I see only the same ProductName/ProductSKU.

See attachment.
Thank you in advance and appreciate your assistance as you did so far.
