After days and days and days of self instruction and trial and error, I finally
finished my flash file. When I play the file on line, it disappears after the
last frame. I can't figure out how to STOP the file after one time thru and
keep the final frame visible .... I can send a link to the file if that would
help. Many, many thanks in advance.

Just add this to whatever frame you want to stop on.

stop();
