The Value expression for the textbox ‘Name_1’ uses an aggregate expression without a scope

I dragged controls from two different datasets.

On dataset feeds a table and other controls are just to show a few values.

When I run the project, I get following error.

The Value expression for the textbox ‘Name_1’ uses an aggregate expression without a scope. A scope is required for all aggregates used outside of a data region unless the report contains exactly one data set. D:\Accounts\rptPrintDrawings.rdlc

Please advise.

It seems like you are using more than one dataset / datatable in your report
Specify a scope for the text box

Here's an example of a textbox value without a scope:
=First(Fields!xxx.Value)
(does not have a scope, valid if only one datatable / source is attached to your report)

If you have multiple tables, specify it using the scope Eg:
=First(Fields!xx.Value, "DataSet1_DataTable1")
=First(Fields!xx.Value, "DataSet1_DataTable2")
