access help

[davidof6128]

I want to design a simple procedure in access... i havent use it for years so ....
I want help how to start....

The idea is to have a program running and showind 50 boxes with products written on them...
when you press one button (name of product xxx) then this starts to calculate ..if i press 4 boxes its box may have its value and when i press sum it prints the sum of the products i choose.

simple ... tell me please what is the general idea of making that possible
what relationships i need etc...
