and I got this messege on the detail :
Warning: The Value expression for the textrun ‘Textbox6.Paragraphs.TextRuns’ uses an aggregate function on data of varying data types. Aggregate functions other than First, Last, Previous, Count, and CountDistinct can only aggregate data of a single data type. (rsAggregateOfMixedDataTypes)
