[rsRuntimeErrorInExpression] The value expression for the textrun ‘Textbox1.Paragraphs[0].TextRuns[0]’ contains an error: Input string was in a correct format.

In this scenario, the expression for the textbox was =”Total Value: “ + Fields!TextBox1.Value

Changing that to =”Total Value: “ + CStr(Fields!TextBox1.Value) will fix the issue.
