Why can't i connect these pins?

attached is a screenshot of some of the set-up i have.

why can’t i connect the pins that are both labeled “file index?”?

as far as i know they both carry ‘value’ type data… evidently, i’m wrong but what is right?

sooner or later everybody will come to this question. if you connect those pins you have a feedback. the soultion is to connect a FrameDelay (Animation) in between. here is some further reading: Creating Feedback Loops.

thanks tonfilm - the loop thing occured to me, and i forgot to mention that it worked if i disconnected something in the little “loop”.

but it’s not a feedback loop is it? because the value of the slice index is not affected by any of the output values of the ‘filstream’ node.

but, yeah it works, of couse.
