"Hi
Thanks for your website! I am a beginner at programming. 
I work for a school that uses a wide range of printers. 
One of our challenges has been to keep track of stock levels and usage rates. 
I then decided to design a database in MS Access (I had been using excel spreadsheets) 
to keep track of all this info. 
I have confused myself a bit and wanted to check with someone who knows what they are 
doing to see if what I am doing below is on the right path?
Thanks for your help
Tatenda
