Update an attribute in a record

Question

I am having a challenge with Access 2016.

I have created a button to update one attribute with another. Example: QTY Value Quantity Request Value Remaining Stock Qty Value

I want to use a button to update the QTY value with the remaining stock qty value.

Private Sub Command67_Click()
Set QTY = QTY - QRAmount
Update Form_PartRequest
End Sub

But when I click the button nothing happens. What I'm missing?

Answer 1

If "attribute" means a field of the table the form is bound to, then:

Private Sub Command67_Click()

    Me!QTY.Value = Me!QTY.Value - Me!QRAmount.Value
    Me.Dirty = False

End Sub

Rename the controls to something meaningful.
