Begginer-Field calculation

[sph]

I have made a simple inventory database containing stock
codes and qty. How can I update the qty field with a
subform??

I assume that you mean Form, because Subform assumes you already have
something working, but you don't say what.
Create a form and bind it to the data table (you can do it using a
wizard which will ask you to select a table / query as the form's record source).
