Hi there,

is there any way to start a macro, once the contition of the if-function in
the worksheet turns true???

greetings and thankst

THW

No, but you could use event code to monitor the cell

Private Sub Worksheet_Change(ByVal Target As Range)

On Error GoTo ws_exit:
Application.EnableEvents = False
If Target.Address = "$H$1" Then
With Target
'do your stuff
End With
End If

ws_exit:
Application.EnableEvents = True
End Sub

'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.

Good afternoon Thw

A cell cannot kick off a macro, but you could use an event procedure to
do something when the cell changes - paste this code into your worksheet
event pane and replace my msgbox with your code. And remember that my
code is checking for the value of cell A1 being false - your post
doesn't state which cell you want to watch.

Private Sub Worksheet_Calculate()
If Range("A1") = True Then
MsgBox "Cell A1 is true."
End If
End Sub

hi dominicb

thank you for your reply, but my problem is not to be notified if the value
of a cell IS true, i need to be notified WHEN it's value changes to true

greetings

I'll try again specifically

Private Sub Worksheet_Change(ByVal Target As Range)

On Error GoTo ws_exit:
Application.EnableEvents = False
If Target.Address = "$H$1" Then
With Target
if .value then
Msgbox "true"
endif
End With
End If

ws_exit:
Application.EnableEvents = True
End Sub

'This is worksheet event code, which means that it needs to be

'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.
