I can't seem to figure out how to alternate the bgcolor for each row

can put two rows of information and loop that? Here's what I have so
Instead of tracking an odd/even row number, you can initialize two
colors before the loop:
my ($ca, $cb) = ('red', 'green'); # Christmas-y!
Then inside the loop, always use $ca for the color, and just swap the
colors after you use them:
while (...blah) {
print qq[<tr style="background: $ca">];
($ca, $cb) = ($cb, $ca);
}
