InputEnabled allows yout to disable editing of a field based on a formula's value, ie when something is approved you can disable editing on fields by setting the input enabled formula for each field to be Status="Approved". In Notes 7 this works on all Notes fields as well as Native OS style.

This is a problem if you have been designing for Notes 6 in a notes 7 design client.

I'll have to use read write access controlled sections instead or a hide formula.

NB in an Input Enabled formula it is best to put a field value in there instead of a formula, and then use

the field to have the formula.
