如何在此 SSRS 表达式中“指定数据集聚合”？

Question

I need a row value in my SSRS report that is a calculated one based on a couple of fields that are already being used in the report. I want it to display in the textbox named 'textboxPercentageValue'. In semi-plain English, the expression/formula is:

If the value of the "Week" field is "WK1", display the value of the Variance field divided by the value of the Price field; otherwise, just display the value from the Variance field.

In VB script gobbledygook, the expression/formula I've add to textboxPercentageValue's Value propert is:

=IIF((Fields!Week.Value="WK1"), Fields!Variance.Value / Fields!Price.Value, Fields!Variance.Value)

Yet, when I try to upload the.rdl file to SQL Server Reporting Services, I get:

" The Value expression for the text box 'textboxPercentageValue' refers directly to the field 'Week' without specifying a dataset aggregate. When the report contains multiple datasets, field references outside of a data region must be contained within aggregate functions which specify a dataset scope.

So what do I need to do to make this expression/formula unambiguous to SQL Server Reporting Services or the VBScript parser or "whoever" is complaining about it?

A text box can get knocked out of its context and still appear to be in it. I came by this post looking for the same error message and it was one textbox in a series of several and it had worked just moments before I had readjusted formatting. After getting the info in the first answer, I went back and poked around and found the textbox throwing the error was actually be the list box but appeared to be on the same levels as the others unless I was trying to move or resize the list box. Moving the textbox out and dropping it back in fixed things. As someone coming upto speed on SSRS from a programmer prospective, the insight in the first answer solved a frustration that has come up repeatedly!
