Linking Between Pages

i have two pages titled: abc.html and program.html. in "abc.html", i have an image and a submit button. the image is a link that when clicked takes us to "program.html" page
in program.html, i have a form with select tag and some options. i have a function (say choose()) that displays the results as a new window.

now i want this choose() function to be executed only when the user clicks on the submit button in the page abc.html. how should i proceed? the sequence of program execution is as:

1) the user is first displayed with the page, abc.html having an image and a submit button
2) he clicks on the image present in this page and is taken to the page "program.html"
3) in program.html page, he has a form with select tag
4) the user just chooses his option and then clicks on a back button and returns to abc.html
5) here he clicks on the submit button and a window that displays the options he has selected is to be displayed.
