Calvin,
First, if you're editing or entering data directly into your table...
that should be avoided. That's what forms are for.
A table has no events, like a check box AfterUpdate event, on which to
trigger your code.
Setting a checkbox to True on a form, would fire the AfterUpdate event,
and your code to calculate the ServiceDate would run there.
If MyCheck = True Then
ServiceDate = 'your calc here
Else
'whatever you might do for a false...
End If
But, that calculation, which I assume, is calculated from stored table
data, should probably not be a saved table value. As a general rule, don't
store calculated values in a table that can be "re-derived", or calculated,
"on the fly", in any subsequent form, query, or report... from data you
already have
Better to use an unbound calculated field to always display the
calculated ServiceDate, on your form or report.
