Form data not recorded into table

[Skyjunk]

I am making a Invoice registration DB. In the Form I have made a entry “VAT =” calcultated as “ NetAmount + VAT%”. The result shows in the Form, “NetAmount” and “VAT%” which are manually entries are recorded in the table but “VAT” is not recorded in the Table.

What could I be doing wrong?

Typically, if you can calculate a value there is no need to store it in the table. Just recalc when necessary
