which creates a collection where each column from TestList is a table. e.g. Student.Grade1 will have multiple entries in the Sharepoint list. This means the chart won't use the ChartTest collection as it expects numbers rather than tables:
"The property expects Number values, but this rule produces incompatible Table values"
and I can't seem to tell it to use ChartTest.Grade1.Value for the Y axis. What I need is the tables from the filter turned into a collection the line chart can read.
