The problem is almost certainly not in the $FmtPV array itself,
but in whatever is handling the resulting value of {$Whatever}
that is splitting on spaces.

For example, if you're wanting to pass {$Whatever} to the value=
parameter of (:input:), and {$Whatever} contains multiple words,
you would need to do:

    (:input text name=abc value="{$Whatever}" :)

so that after the page variable substitution PmWiki sees

    (:input text name=abc value="Two words":)

and not

    (:input text name=abc value=Two words:)

which is treated as

    (:input text name="abc" value="Two" words:)
