Folks, I have a form that a user fills in and the data creates a new record in the master table. Two of the current fields are TrainingDate and week number. (ATM the user manually works out the week number and inputs it into the week number field). I need to state here that I am a newbie and as such a real novice with Access but Im sure there must be a way to totally remove the week number from the form and have it auto populate in the master table using the date that is input into the TrainingDate. I am aware of the DatePart function but unsure how to implement or eve n if that would be the recommended way to achieve this. Help appreciated..
