Random spawning

I have 7 different objects at the top of the layout (off screen) labeled Spawner1 - Spawner7. I am trying to have 2 different objects (Goodblock/Badblock) spawn randomly at random(1,3) second intervals. I am having some trouble getting them to spawn at random spawners. Any help?

its all just guessing about how your doin it without you postin your capx for us to look at

Lots of ways you could do it. How about this: randomSpawn.capx

Thanks ramones :D I understand how it works now, but what number is dt? Where does it get the number from

dt is deltatime is a system variable for the time it took to complete the last frame

Okay :D Thanks for your help!
