To admins - i wasnt exactly sure where to put this forum post, so please move if needed.
so what i want to do, is when the user viewing the webpage, fills out the form, and hits save. it will edit a particular html file, adding lines of code into that file.
even if you direct me to where i should be looking, i will be closer than i am now, to solving my problem...
You will need to use a server side language like ASP.Net or PHP.
