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
Data
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
