Visual Basics for Access- How do I add fields to a subform based on txt field

[monicad82]

I'm a beginner programmer and was tasked to create a form containing 1) a text box where a user enters number of cars and 2) a separate subform

Some conditions:
-If user enters more less than 1 then prompt msgbox and exit procedure
-If user enters more than 5 then prompt msgbox and exit procedure
-if user enters 1-5 then show the subform and populate fields based on number of cars
e.g. If user enters 3 in text box and clicks button, subform is populated with subform with Car Name field below.
row 1 - "car1"
row 2 - "car2"
row 3 - "car3"

This needs to be accomplished using DAO - Any ideas?
