You can put the same field on both layouts. You can format the field on one layout with a value list of all 6 options. On the other layout, you can use a different value list with just the last two options.
I'm sorry, I can't seem to figure how to do that.
How is your current value list defined? Is it custom values?
Are both of your layouts based on the same table? (Do they have the same name selected in Show Records From in Layout Setup?)
It is custom values.
Both fields are based in the same table.
Open your current list of custom values in Manage | value lists.
Copy the last two values to the clipboard.
Define a new custom value list. Paste the copied values into this new value list.
Go to the layout where you want to see only the two check boxes and enter layout mode.
Select the field and use the Inspector's data tab format this copy of the field with the new value list.
Thank you, that did it.
