here is something that has been causing be problems
for us newies: when you declare a global variable you can access it anywhere (along the timeline just by name) or within another movie with dot/syntax. so _global.varName can be accessed anywhere using just varName. But what I didn't know was in order to change the value you had to use the _global.varName decleration. if you try to change the value w/out it you create a totally new variable in the timeline of the current movie clip with the same identifier. And when that happens the timeline based variable takes presidence. This can really knock things around if the movie clip is in a loop.
for the veterans besides knowing what not to do, how can I use this to my advantage?
