    Smile Move start

    Hi

    I'm about a new as you get and its probably easy for most of you. Here's my problem. I need to get the falling snowflake script to start farther down the page. Whether it looks nice is not a concern. I just need to know what to add or change. My main goal is to have it starting in a table(html) or just keep it from crossing over the Header of the page. Heres the code.
    Code:
    <script type="text/javascript">

    Thanks for looking and help in advance.

    Code:
        yp[i] = Math.random()*(doc_height - x) + x;
    ... where x is the number of pixels from the top. It's bad that the script only allows pixels, but that's the best we can do without heavy modification.

    Changing the X variable doesn't change the start point. Maybe I'm not changing it correctly. Can you give an example of the change. I put yp[i] = Math.random()*(doc_height -100); trying to get the snow to start 100px from the top The snow still comes from the top of the page. I really would like to know if there is a way to stick it in a TABLE. So the snow would only show up in that area of the webpage. There is a new copy of the script maybe that is easier to change.

    <script type="text/javascript">

    It's the same. You missed the rather vital + 100 part.
