Use lexical parameter.

In the After Parameter Form trigger check whether "from" and "to" date have been entered. If yes then lexical parameter would look like

lex_param := 'and b.start_Date between ' || :frmdate || ' and ' || :todate;

Else,

lex_param := 'and 1 = 1'

See Reports Online Help System for more details; also, search the board - there've been topics which show use of lexical parameters quite well.
