Thanks Noah! That worked.

Can anyone shed some light on:


A few more questions - the doc link that I just mentioned shows:

GotoIf(condition?label1[[:label2])

What are the [[ before :label2? There are two opening square brackets, 
but just one ] closing? Is that a typo?

Also, the doc shows:

GotoIf(condition?[label1]:label2)

Why is label1 in square brackets and label2 isn't?


Thanks!
Markus
