I have a popup calendar for form field, and it works great in IE but FF tells me "Error ! The current browser is either too old or too modern (usind DOM document structure)." and shows part of this calendar in the bottom of the page permanently. Is there any way to disable execution of this script if user is in FF browser so he can just manualy enter the dates? Appreciate any help!

Why not simply make the outdated script work in all browsers?

Elena I agree with Chris that the best solution is to recode the script itself so it does work.

However the easiest solution might be to use conditional comments to only include the script when the browser is IE. You could also try some browser detecting JavaScript to only display the script for IE. The conditional comments will probably be easiest, though.

But again the best solution is to rework the script so it works across browsers.

Guys, thank you for the advice, I'd love to do it, I just don't know HOW!!! I'm kinda new at all this... Would you be willing to help?

I'm sure we could.
However we need the location of the code, so a URL would be handy.

Cool!

There is a script in the bottom of this page:

(oh, one more thing: Tour field glitches in IE but looks fine in FF & NN, any ideas why?) Yeah, I also installed Netscape

The calendar itself is here:

And one more (sure not the las one ) question: I'm using this code in the page to have gradiend background:

{body} style for a gradiend background:
filter: progid:DXImageTransform.Microsoft.gradient(enabled='true' ,startColorstr=#FFF9AF, endColorstr=#78AEFF, gradientType=0)

It works only in IE, are there any ways to have something like this in other browsers?

ok, that green face is not part of a code, it should be ":" followd by "D"

and to prevent next question: I tried to e-mail the person, who wrote this script, the letter came back undelivered...
