Another error I hit

Warning               1

[rsRuntimeErrorInExpression]

The Value expression for the textrun ‘Textbox28.Paragraphs[0].TextRuns[0]’

contains an error: Overload resolution failed because no Public ‘/’ can be called with these arguments:

‘Public Shared Operator /(d1 As Decimal, d2 As Decimal) As Decimal’:

Argument matching parameter ‘d2’ cannot convert from ‘TextBoxImpl’ to ‘Decimal’.

C:\Projects\Reports\1. Report.rdl

Thankfully Google found Qiuyun answer. I was missing the .Value at the end.

So (wrong)

=ReportItems!Textbox1

Fixed (working)

=ReportItems!Textbox1**.Value**
