Hi!

I usually have a method on the form called "RefreshButtons" or something like this. The reason that in the future you probably require something similar for otehr buttons etc. etc. and putting tonnes of the same code into LostFocus of each control is nto a good idea. Just call that form's method, and the rest will take care the code in there (check for valid conditions to enable/disable buttons, for example). The code in my method looks usually as follows:

With thisform.MyButtons
  .Command1.Enabled = !empty(thisform.txtMyTextBox) AND ...
  .Command1.Caption = "Add " + iif(thisform.cboTypes.ListIndex=1,"Somethin 1",iif(...))
EndWith

HTH.
