Trying to export a older flash file in player 8, having issues.

Question

i have this flash file that is written for player 5. i had to
republish in player 8 to take advantage of the anti aliasing
features available, however, i seem to have a problem with a
secondary swf that gets pulled in to the main movie. the secondary
swf targets player 5 as well. when i republished for player 8, i
got these compiling errors. can anyone tell me why this won't work
if i publish in 8, but works publishing in 5?
while (Number(n)<19) {
n = Number(n)+1;
bn = "kv" add n;
duplicateMovieClip("kv", bn, n);
setProperty(bn, _x, Number(getProperty(bn,
_x))+Number(n*getProperty(bn, _width)));
setProperty(bn add "/b", _x, getProperty (bn add "/b", _x) +
(random (20)+1));
it must be a syntax issue as the original code is AS1.0. Does
anyone know what this would need to look like to work publishing
for player 8?

Answer 1

The only real problem is that "add" is no longer supported.
It should be:
while (Number(n)<19) {
n = Number(n)+1;
bn = "kv" + n;
duplicateMovieClip("kv", bn, n);
setProperty(bn, _x, Number(getProperty(bn,
_x))+Number(n*getProperty(bn, _width)));
setProperty(bn + "/b", _x, getProperty (bn + "/b", _x) +
(random (20)+1));
But this will have yet another problem if the "n" is not
defined prior to the while loop. Flash 5 assumed undefined
variables were 0. Flash 8 assumes undefined variables are
undefined.
But a newer and improveder version of the script would be
something like:
