Jason, Ignore thread 15, above. I used the Framework plug-in and was able to successfully built the result page showing the Parent table and the child table.
However, it has thrown up further questions as follows:
1. I can't search on the child table - I may want to see whether a family member is a member. This must be something to do with the filters I had to set in the child table as per the documentation. Do you have to create a new search via the search wizard if you just want to search the child table - without the filters?
2. If I insert a family into the 'Parent Table' and that gets, say an ID=30, and then I do a search to find another family in the Parent table say with ID=28. I get the results for ID=28. However, the Id from the previous insert namely ID=30 is still retained in memory, because if add a member to family ID=28 it populates the child table with ID=30 and not ID=28. What have I done that's not correct?
