This is what the tabels look like:
**Product** |**tblReview** | **tblComment**
ProductID | ReviewID | CommentID
Name | Description | Description
Year | GroupID | GroupID
Price | Grade |
GroupID
GroupID is name_year of a Product, ex Nike_2010. One product can have diffrent sizes for exampel:
ProductID | Name | Year | Price | Size | GroupID
1 | Nike | 2010 | 50 | 8 | Nike_2010
2 | Nike | 2010 | 50 | 9 | Nike_2010
3 | Nike | 2010 | 50 | 10 | Nike_2010
4 | Adidas| 2009 | 45 | 8 | Adidas_2009
5 | Adidas| 2009 | 45 | 9 | Adidas_2009
6 | Adidas| 2009 | 45 | 10 | Adidas_2009
I dont get the right count in my tblReview and tblComment. If I add a review to Nike size 8 and I add one review to Nike size 10 I want 2 count results when I list the products with diffrent GroupID. Now I get the same count on Reviews and Comment and both are wrong.
I use a datalist to show all the products with diffrent/unique GroupID, I want it to be like this:
______________
| |
| Name: Nike |
| Year: 2010 |
| (All Sizes) |
| x Reviews |
| x Comments |
| x AVG Grade |
|______________|
All Reviewcounts, Commentcounts and the Average of all products with the same GroupID, the Average works great.
