I tried both of these options and get two different errors. For the first option you gave me. I get an error that states:
[rsAggregateOfNonNumericData] The Value expression for the textrun ‘CL_WOM_OWN_FL2.Paragraphs[0].TextRuns[0]’ uses a numeric aggregate function on data that is not numeric. Numeric aggregate functions (Sum, Avg, StDev, Var, StDevP, and VarP) can only aggregate numeric data.
And the second option gives me this error:
[rsRuntimeErrorInExpression] The Value expression for the textrun ‘Textbox40.Paragraphs[0].TextRuns[0]’ contains an error: Input string was not in a correct format.
