Ok since my of my issues have been resolved,I was flying through the code, until now: I've now run into one I cant even find anything on Google for it. Here's the text of the error:

Error 3004: Problem in mapping

fragments starting at line 937:No
mapping specified for properties
StoreItem.ItemPrice in Set StoreItems.
An Entity with Key (PK) will not
round-trip when: Entity is type
[psychoco_GodsCreationTaxidermyModel.StoreItem] F:\Projects\GodsCreationTaxidermySVN\GodsCreationTaxidermy.Data\GCTEntities.edmx 938 945 GodsCreationTaxidermy.Data

Of you need any code samples let me know

The error means that your table imported to the model contains additional column ItemPrice which is not mapped to your entity.
