String to number with decimals (but without separator)

Your code actually works perfectly outside of my subflow (below). This is what I'm trying to do.

I am using this:
https://flows.nodered.org/flow/43501a1b424434de0ffb

To iterate over an array line_items where there is a key named total inside each object.
For each iteration, I am using a change node to change total into netPrice.

change

This works perfectly.

Then I need to convert that value (netPrice) into the forementioned format.

Tried placing the function node here, but that did not work:

nr

Placing it before or after my subflow doesn't work either without specifying which object.
