See if you can save your script pages to html. If you can, save to html, then copy and paste from the html file using the html tags.
Note: This doesn't always work. Depends on what kind of software your using for your script.
html tages:
[ type HTML in these brackets ] before pasting.
after pasting [ type / then HTML in brackets ]
Should give you your scroll bar. Hope it's not too confusing.
