Kind of confused what you're asking. You want to push a button on the main form to increment a date on a subform? If that is the case, you could just add a checkbox to the main form next to the buttons like SubformCheck, and then use an ifstatement in your buttons

If SubformCheck=True Then
'set the field to increment to the subform field name
Else
'do the increment on the normal fields
End If

If you were going to use multiple fields, you could use a combo box to pick which subform/form you wanted to change, or you could push a button inside the subform to send a number to an invisible textbox on the main form and identify the form that way. There's a million ways you could tell it which form to work on, I'm just not sure what you're trying to accomplish. Upload pictures maybe?

Access Calendar Control

So you want a way to highlight a control that will have the date entered?

Just pass any control to the function that I build in the extended cut and it will work with any field.

Hi Alex,

Have you used the Sage programmes, the best way I can think of is..

Sage has a Sales Ledger, Purchase Ledger and Stock Control.  Within each module there is a "Save" button, "New", "Advance", "previous" buttons.

Can I create for example just 1x "Save" button and copy and paste that into each form I design/Make or does that button need to be created from new as if it didnt exist.  I understand that I may need to tweak the coding to each form, but the action is still the same on each module.

Thanks

Does the Save button have logic per form?
You can make global modules that have functionality you could re-use anywhere but you'll still have to hook up the button on each individual Form and call that Sub.
