repeating sub vi

[cgama]

Hi

To make my VI look cleaner I decided to combine 4 low pass filters in a sub VI, and use this sub VI 3 times.

The problem is is seems to be adding them together instead of giving me 3 individual groups of signals.

Is there a setting that I am missing?

Thank you for your time and help!

Did you make the subVI re-entrant?

Thank you very much! I knew it had to be a small thing.
