Hi Karsten, so from a quick look over it, you need to modify how you're setting input index number 2:

Array curve input 2 is the mode, it can be either 'NumItems' or 'Distance'. Don't use 'ArrayCurveDistance' - that's something separate from the factory, the ArrayCurve.js script stores a property for 'ArrayCurveDistance' to remember the last used distance to re-initialize the distance the next time the command is run.

Array curve input 3 is an integer for the number of items in 'NumItems' mode.

Array curve input 4 is the distance value for 'Distance' mode.

Let me know if you are still stuck after that.
