Pop up messages

[rudi7109]

I have three fields:

Truck
Start time
End time



Then Calculation field = minutesatediff("n",[starttime].[endtime])

I want if the minutes on my calculation field reach 60 a popup message must appear saying Truck??? is at 60min with a accept button

Triggering a 'popup' (InputBox or a form ?) requires an event. A calculation is not an event. Could use the BeforeUpdate or maybe AfterUpdate events of the 2 time fields.
