[FMX] Timed release of random snow (noob)

Hi,

I’m working w/the snow effect so nicely put up here:
http://www.kirupa.com/developer/actionscript/snow.htm

I’m trying to modify it into a slow build of snow to go w/some text that drops in. Like 1 flake falls on frame 1, 5 flakes fall on frame 50, and a flurry falls and loops on frame 100 when the text stops and sits.

I made my snowflake into a movie clip and put the random movement actionscript in there. Then I dropped this clip once on frame 1, 5x on frame 50, but…

how do I get the big build up at the end? I am so stuck.

thanks
erica
