See the Default Value

In Access you can specify today's date as Date()
Also a day is equal to 1.  So if you want to have your expiration be tomorrow
your default would be Date()  + 1, one week from today  Date() + 7

There are many date functions but that is the simple explanation.  

I don't see that you have watched any of the courses yet.
Start out by watching Access Beginner 1 It is FREE.

I have watched those from Mr. Rost, but what I want is being able to update a date set in a module as expiry date from a table , for example I create a table called ExpiryT and a Form ExpiryF and also I have a module called system expiry on which module I have a function called Expiry, this function expiry () I call it on from the form onLoadevent , when this form loads of the data is today then the user will get a message as system license expired, am using the database personally but some people are purchasing it from me so I want an easier way to up date thier licenses without always going back to the module and change the data. Thanks

Hope u have got my cry
