How can I make my function result in an error

[Michelle]

I'm writing a UD Function, and if the user enters a range wrong, I want the
function to result in #VALUE or #N/A.

How do I code that into my function?

Thanks

Function MyFunc()
MyFunc= CVErr(xlErrValue)
'or MyFunc=CVErr(xlErrNA)
End Function

From VBA Help:

Cell Error Values
You can insert a cell error value into a cell or test the value of a cell
for an error value by using the CVErr function. The cell error values can be
one of the following XlCVError constants.

Constant Error number Cell error value
xlErrDiv0 2007 #DIV/0!
xlErrNA 2042 #N/A
xlErrName 2029 #NAME?
xlErrNull 2000 #NULL!
xlErrNum 2036 #NUM!
xlErrRef 2023 #REF!
xlErrValue 2015 #VALUE!


Example
This example inserts the seven cell error values into cells A1:A7 on Sheet1.

myArray = Array(xlErrDiv0, xlErrNA, xlErrName, xlErrNull, _
xlErrNum, xlErrRef, xlErrValue)
For i = 1 To 7
Worksheets("Sheet1").Cells(i, 1).Value = CVErr(myArray(i - 1))
Next i

This example displays a message if the active cell on Sheet1 contains a cell
error value. You can use this example as a framework for a cell-error-value
error handler.

Worksheets("Sheet1").Activate
If IsError(ActiveCell.Value) Then
errval = ActiveCell.Value
Select Case errval
Case CVErr(xlErrDiv0)
MsgBox "#DIV/0! error"
Case CVErr(xlErrNA)
MsgBox "#N/A error"
Case CVErr(xlErrName)
MsgBox "#NAME? error"
Case CVErr(xlErrNull)
MsgBox "#NULL! error"
Case CVErr(xlErrNum)
MsgBox "#NUM! error"
Case CVErr(xlErrRef)
MsgBox "#REF! error"
Case CVErr(xlErrValue)
MsgBox "#VALUE! error"
Case Else
MsgBox "This should never happen!!"
End Select
End If
