Trigger a custom function in a Zoho Sheet on range change

Trigger a custom function in a Zoho Sheet on range change

Hello,

I have a custom function in Zoho Sheet that updates a Zoho CRM record. That by itself works. I am trying to trigger that function when a new row is added to the sheet. I thought this would be able to happen via the VBA editor, but I can't get it to work. It did work when the cells were hard coded, but then when using offset I couldn't get it to work. 

I have pretty much no experience with VBA. But here is what worked:


REM Sheet Module

Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = false
On Error Goto ENEV
REM add your code below

Set watchRange = Range("L2:L1000")

If Not Intersect(Target,watchRange) Is Nothing Then

  If Target.Value <> Nothing Then

    Range(M2).Select
    ActiveCell.Formula="=_CREATE_UPDATE_OPP(A2,C2,D2)"

 End If 

  End If 

ENEV:
Application.EnableEvents = true
End Sub


When I attempted to enter offsets, so that it would get the values from the newly added row, I had no luck. No idea what I'm doing, just tried to use offset as I read about it in another article. 

Didn't work: 


REM Sheet Module

Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = false
On Error Goto ENEV
REM add your code below

Set watchRange = Range("L2:L1000")

If Not Intersect(Target,watchRange) Is Nothing Then

  If Target.Value <> Nothing Then

    Range((Target.Value).Offset(0,1)).Select
   ActiveCell.Formula="=_CREATE_UPDATE_OPP(Target.Value.Offset(0,-11),Target.Value.Offset(0,-9),Target.Value.Offset(0,-8)"
 End If 

  End If 

ENEV:
Application.EnableEvents = true
End Sub


I also tried () around each offset reference. There is probably a way better way to do this, so if so, disregard what I've started. Thank you for your help!
