Although there may be reason to do this assignment to $FmtPV within a
function called by markup ... it would be fairly complicated and you
would have to carefully judge the order of rules and when the PV was
going to be used and etc.  (And by all means $FmtPV would have to be
declared global in your function.)

Typically, however, you would initialize $FmtPV outside of any
function so that its value is available from then on.

This is in addition to the necessary changes suggested by DaveG.
