>This is the easy part . My real big problem is when I create the screens . The field somehow need to show like two fields . On where the dozens part will show and one where the pairs part will be with a little label in the middle for the dot. I suppose too that I will need two variable ( properties) to hold this data. I that write ?

So your form will have two textboxes, populating with
Thisform.Text1.Value=28 && or some other calculated number
Thisform.Text2.Value=06
