Making hi scores upload to web page

[jon]

Hi
I am a beginner/hobbyist

I would like some advice please, I have never used livecode to upload or download via ftp.

I have a stand alone game with hi scores feature. It works well in the standalone.
I can create a web page on my server called hiscores.html

What i need is a user to be able to upload a hi score to hiscores.html. Should I download the webpage, then do calculations within the
stand alone, then overwrite/upload the changed html page, I have looked around for answers but I am not sure at all of the best/easiest way to do this.

I am thinking of tables on my web page with scores and names next to them, (my html is ok)
but I don't have much idea how I should work the updates of hi scores, also is ftp secure (can people access any other files on my server if i do this?)

Sorry if it's a very basic question, I am just wary screwing things up.

Thank you, Jon
