Refreshing a card

[Terry Judd]

Mark - if you want to do a general refresh the card then just call openCard
in your handler. If all you want to do is refresh the date stamp object then
add something like...

Set the visible of grp/fld/whatever "dateStamp" to the showDateStamp of this
stack

...to your case statement

HTH,

Terry...
