Hi Samuel.

There are several ways you can do this one of them would be:

In the valid event of txtsales:

here you would do all your calculations and the result should be the value of
txtgst.
e.g.

sum all (whatever) to total
txtgst.value = total
thisform.txtgst.refresh()


as I said this is just one way of doing this.

I hope it helps.
