For the Layout of the page, I was trying to put text above the EVENTREGIS call, like so:
"This is the top text
{EVENTREGIS}
This is the bottom text"
For some reason it kept putting the top text below the event information. I made a few changes to the code, and the top text now appears at the top. All changes are marked under the comment 'FIX INLINE DISPLAY'. Its kinda hastily thrown together, but it works.
