Just a guess:
You're executing 'getValue' _after_ page-level 'display' processing has
begun. It is variable, but, by default, page fields are cleared before
page-level 'display' processing begins.
You might want to try executing 'getValue' as part of the event method that
executes when your 'recalculate' button is clicked, and put the results
into an instance variable for later use during 'display' processing.
