I'm still new to WFA, so this question probably has an obvious answer I'm overlooking, but I'm trying to grab a value out of a table comprising three columns: Aggr, Cluster, SVM. I've tried referencing them using the following ways:
getValueAt2D($table, row, column)
...and a plethora of other ways. I don't understand what I'm doing wrong; my coworker's workflow can locate the resource in his table using getValueAt2D(), and since I've tried copying it verbatim, I'm really stuck.
Here is the error it's throwing:
Failed to evaluate resource selector. Illegal expression: getValueAt2D($table, row, column) ...or whatever other function I happen to use to try and evaluate the value.
Appreciate the help.

Thank you for your reply. It looks like the reason for this error was that I was populating a field with a default value, because when I manually input my values, it stopped throwing the error. Kind of frustrating that WFA behaves like this sometimes...
If it has worked for you, fine then. But WFA doesn't behave in any random manner, there is a logical explanation to every error thorwn.
If you had provided your workflow, I would have been able to give the convincing reasoning. Like I said, designer issues are difficult to debug just with words, the possibilities are too many.
Thanks for your replies. Now that you mention it, it would be good to know why it behaves in this manner. When using the create export rule command, I have this table to evaluate some of my values with. The Client and Policy field is a string, and the rest are enumerations. When the Policy field is populated with a default value it gives me the illegal expression error, but when I type it manually, it executes normally. Thanks.
