I have a set of data I want to display as a matrix.
Along the top are three column headings (P, M, D).
In the first column are the row references, which are numbers 1 to 10.
Where these row and column references cross is a lot of text.
Basically I can then identify P1, M3, D5 etc (battleships in a way).
I have created this as a crosstab query with no issues.
The key field for this query is set as unit_id (NOT used in the actual crosstab table but I can set this to, say, 44 and the table shows the results for course 44).
I have a form that lists all the courses and has the key field unit_id.
If I try to embed the query into the form the system proposes connecting unit_id to unit_id but then says it is not in the query. If I set to define my own I find that, sure enough, the unit_id query is not showing - though it IS in the query.
What can I do to connect the form to the crosstab query using the key field unit_id?
