make a value visible or not based off the result

[Guest]

How in a report do I make the text box and label not visible if the result of
the calculation is =0 or =null?

the text box name is 'bloboatt' and the label name is 'label595'

On the OnFormat event of the section where the text box is located in write
the code

If Nz(Me.CalculationField,0) = 0 Then
Me.[bloboatt].Visible = False
Else
Me.[bloboatt].Visible = True
End If

Or to make it shorter

Me.[bloboatt].Visible = Nz(Me.CalculationField,0) <> 0
