Group Line plot error

When I try to use the Group Line Graph in my project, I get the following error message "ERROR: Unable to get SAS code. Object reference not set to an instance of an object."

I've traced the cause of the error back to a Join and Query step, which I have filtered out data and rejoined, as in the following example


A 1
A 2
A 3
B 1
B 2
B 3

I filtered the original data, and made 3 data sets that were

A 1 A 2 A 3
B 1 B 2 B 3

Then I rejoined the data so it is now:

A 1 2 3
B 1 2 3

It's during this final step that the group line plot error will occur.

Hopefully, someone can make more sense of my explanation than I can from this error.

Thanks in advance for the help
