Sorry, not correct... as you can see in CR Designer the name of the formula has an @ sign in it.
Right Click on it and rename it and remove the @ sign.
As for the curly brackets that is normal, you cannot use them in the name of the formula.
In VS if you set location to the data xml files for the main report you'll see it only has the on Unit table, add the rest then the linking table will be enabled.
Why do you need the linking tab if these reports work?
