Question

I have a report with a field whose value was the expression:

Fields!TotalPrice.Value/Fields!TotalSlots.Value

Although sometimes TotalSlots

Jamie F's answer is correct. As a tip, you can add a function to your report code to make the division a bit easier to implement in multiple cells, e.g.

Public Function Divider (ByVal Dividend As Double, ByVal Divisor As Double)
If IsNothing(Divisor) Or Divisor = 0
  Return 0
Else
  Return Dividend/Divisor
End If
End Function 

You can then call this in a cell like so:

=Code.Divider(Fields!FieldA.Value, Fields!FieldB.Value)
