i m looking for how form Oracle9i form builder:
pass values to a html web page
and
execute a trigger written on a button as well in a html web page.

In detail:
there is web page called metar_taf.html has:
metar text item which contains airport code fox example (OLBA, LCLK, LFPO ....)and
button called submit, if it' is clicked all the metars messages for the airport having a code mentioned in the metar text_item are displayed in a generated html file.
also
i create my form called read_web_file.fmb

My question is how i can through my fmb form:

and
run the trigger already written on the button submit found in the metar_taf.html to generate new html file that contains all airport code messages for (olba lclk....)
