Microsoft Access AfterUpdate Events

Q: I have two fields on my form (HourlyRate and HoursWorked) and I need to calculate a billable service charge by multiplying them together and placing that value in a 3rd field (ServiceCharge). I need to be able to also just type in a ServiceCharge value or adjust it, so I can't just use a calculated field in a query. How can I do this?

A: You can use an AfterUpdate Event in both the HourlyRate and HoursWorked fields so that when they're changed, the ServiceCharge is automatically calculated. You can do this with a very simple one line of VBA code, as long as you know where to put it.

Here is a FREE VIDEO TUTORIAL that will walk you through an example of building an AfterUpdate Event. It's much easier to show you how it's done than to explain it here.

I teach the concepts in this free mini tutorial in my Access 303 course. These are full courses - over 60 minutes in length each. I spend a lot more time going over how to do this, in addition to lots more tips and tricks.
