A For loop structure executing the wrong number of times

[Sebastian James]

Has anyone had any trouble with a for loop executing the wrong number of
times?

I have a for loop in which is nested another for loop.

The outermost loop always executes 4 times, regardless of what is wired
to the 'N'

If anyone has seen such a bug I'd be interested to know about it.

You're not trying to auto-index an array are you ? If you have an
array input into the for loop and keep auto-index on, then the for
loop will run the lesser of the array size or the N.

It sounds like you have an array wired into your for loop set to auto
index. If this is the case, then the loop won't execute more times
than the number of elements in your array (you can wire it to loop less
times however).

To work around this disable indexing in the node at the point where the
array enters the loop (assuming that you don't know this already).
Then, use the "index array" funtion along with the loops iteration
terminal to increment the array.

I hope this helps.
