131811 Vertical Scroll External Text

Straight forward. I have an area for text on an HTML page that is smaller than the text needed to go in the area. I would like to have a scroller, probably javascript, that can be placed in the desired on the page. I would prefer to have the scrolling text in a text file on the site as opposed to placing the text directly into the scroller code. I am in the process of finalizing the page now, if anyone is interested. The width of the scroll area will be about 150px and the vertical about 250px. The font size to be used will be no more than 10pt. I have found scrollers. I have placed them on pages. I would also like to refer to an external file. Any takers that can do a good job, now
