Opening another page on a network drive

i have two forms, one submit data to the second. i have both html files on a network drive, it works fine from my end and the data show up on the second page perfectly , but from another user's end it opens without any data...

this is in the first page:
window.open("second.html?" + data, 'second');

i am not sure if it a url problem, any help will be appreciated.
