Scrolling text-banner from a text-file

[GK5]

Hello,
I'm trying to include a scrolling (left to right) text-banner with information on my webpage.
I have used this code in the body placeholder:

<marquee direction="left" height="75" width="500" bgcolor="white">
<font color="red" face="Verdana, Geneva, sans-serif" size="+5">
Deze avond is er geen bijeenkomst wegens het slechte weer.
</font>
</marquee>

It is working very good as long as I'm using a fixed text (in this case: Deze avond.....).
But since the information is updated at least once a day I would have it in a text-file that would be used by the html-code.
In that case I only have to upload daily the text-file by fpt without changing my Xara web-file.

I've already tried it with the <object> and <div> commands but its is not working.
Since I'm only the knowledge of a beginner for html-tags, I hope someone can help me to solve this problem.

I have included a copy of my test-file so you can see what I mean.

Thanks
Frank
