I am trying to create an application that allows the users to look up pricing and previous "similar items" using a series of cascading lookups. I am running into a problem with importing the data or configuring the tables correctly in order to accomplish this.
I have an excel sheet with information like the following:
Index Year Make Model Trim Status Price
| 21009 | 1999 | Chevrolet | Express 3500 | ALL | 1 | $ 239.00 |
| 21011 | 1999 | Chevrolet | Lumina | ALL | 1 | $ 199.00 |
| 21012 | 1999 | Chevrolet | Malibu | ALL | 1 | $ 199.00 |
| 21013 | 1999 | Chevrolet | Metro | ALL | 1 | $ 199.00 |
The problems I am having is that if I import all of the data into the same table, and then have another table lookup the values, when selecting the year, there are 100 selections for each year instead of just one. If I select one of the years, I only get one model as it is associated with the index field, if i select a different option of the same year, I am presented with a different model as it is associated with the index.
If I put each column in a separate table and then have the main application table look up those, I don't have any real relationship and the prices don't populate as we need.
can anyone give me a push in the right direction here? Maybe a link to some documentation? Have been able to find very little on this feature.
