Want to update a junction table via forms page

2
I have created a junction table so that I can relate data from 2 other tables.

Table 1 - Category Table (has the following fields with data)
CatID (primary key)
CategoryName
CategoryStatus

Table 2 - Names Table (has the following fields with data)
NameID (primary key)
Names
NamesStatus

Table 3 - Junction Table (has the primary keys from Tables 1 & 2 - input manually)
CatID
NameID

If I update the Junction table manually it works but I want to be able to use Access Forms to select the CategoryName and the Names fields from the 2 tables and the application be able to save the primary keys in the junction tables.

Even though you have created a junction table the relationship between the two tables is still many to many and as such cannot be displayed on one form. You will need to create a main form and a subform.

For example ...

Main form based on the Category Table and subform based on the following query.
Expand|Select|Wrap|Line Numbers
  1. SELECT CatID, Names.NameID, Names, NamesStatus
  2. FROM Junction INNER JOIN Names 
  3. ON Junction.CatID=Names.CatID;
  4.
