How to create multiple tracks?

Hi there!

Just getting started with SoundFlow here... I have what might be ambitious plans, but for now I'm just trying to get the most n00b basic script going.

I would like to make 4 audio tracks at once. When I use the

Create New Tracks>Audio Track - Mono

script and choose 4 next to Number fo New Tracks, I get an error when trying to run it:

"Could Not Update The Number Field"

I'm sure I'm making the most basic mistake here?

Thanks for your help!
