Update either dataset or array

Thanks again. I was able to install the module and the recorder function came right up. With that in mind would I just be creating an expression tag of type dataset and the expression would be the recorder function?

Here is what I have but it is not populating...

I have tried four different ways to do the columns and row values including brackets and no brackets and the tag as a string or as a tag with '{}' around them.

Without an example in the documentation I am unsure of how to get it to work.

Do I need to have a separate dataset memory tag and then another expression tag with the recorder function where I can use the dataset in the recorder function versus the colName and colValue?
