Script help for mulitple browsers

[hellays]

Hi everyone
I know this has probably been asked a million times before but I have been searching the net for hours and have not found a solution so I am hoping one of you clever people will be able to help me. PLEASE!!

I am using this snow fall script http://www.dynamicdrive.com/dynamicindex3/rain.htm

It works perfectly in IE but not in Firefox or Safari.

Anyone have any idea how to help? I am not the best with the techno speak so not too complicated if at all possible!

Thank you so much to anyone who can help me out!

this script is not cross browser compatible (as far as I can tell from the first glance) you’d need to replace the used IE proprietary properties by something, that is able to read either ways.

Thanks for your reply, sorry to be so thick but do you know how I do this? I have no idea!!
Thanks

basicly you have to do a conditional block, where you loop through all (mostly 2) known properties to get the value you want.

ex. (the properties may not be correct, just pulling from memory)

// always start with the ECMAScript or W3C standard
if (window.clientWidth)
{
    var width = window.clientWidth;
}
// then test IE proprietary features
else if (window.screenX)
{
    var width = window.screenX;
}
// throw error in case you’ve forgotten something
else
{
    throw new Error("Could not determine browser width.");
}

it may well be that there are such crossbrowser functions are already out there (e.g. there is a bunch of solutions for event handling)
