Pop up reminder that has to do with dates

[Jamdown_Rasta]

good today, i am a novice at ms access database but i do have just a wee bit knowledge. with that said:

i am using ms access 2003

i have created a database. i have a table called tblEmployee
with fields: empId, startdate, duration, releaseDate.

i have created a form to capture these data called frmEmployee. now this is where i need you guys assistance please.

i want a popup reminder to popup up 3 weeks before the releaseDate and a popup reminder to popup on the day of the releaseDate.

i want this to be done for all of the records that are stored in the database.

take in consideration also if the user wants to change the data entered for the duration and releaseDate field.

thanks in advance.
