Having Issues Using Splines

Hey all! I am currently having some problems using the splines. for reference this is the tutorial i am following.

at the 19.46 mark Zak mentions testing that the splines connect and add to the array, When I try this, instead of adding another element, it will just literally copy and paste. For reference, this is what my blueprints and structure look like

Thank you very much in advance :slight_smile:
