Alert Message

[johnceef]

I am using a time and attendence form which has to sub forms. The main form
has a field which contains an employee's scheduled hours. sub form #1
contains the employee's actual hours worked for the current pay period and
also has a sum of the total hours worked. I would like to create some kind of
alert informing the data entere that the two fields are unequal if in fact,
that is the case. I do not want this message to unallow the data enterer to
move on to the next employee. I just want him / her to be aware. (Access 2002)

Any help would be greatly appreciated.

Thanks in advance.

John
