Apexchart helper problem

Hi guys and girls!

I am trying to create an ajustable Y axis / horizontal bar that is adjustable with a helper.

input_number.prijss is my helper so adjustable.
When I set for Y 0.10 it is showing my red line, but when I set Y 0,10 it doesn’t
Helper is also showing in x,xx, tried to change system settings but does noet work.

This is my code:

type: custom:apexcharts-card
graph_span: 24h
apex_config:
  annotations:
    yaxis:
      - "y": input_number.prijss
        borderColor: red
        label:
          borderColor: red
          style:
            color: "#fff"
            background: red
          text: Grens
experimental:
  color_threshold: true
header:
  title: Energy prijzen vandaag MET extra kosten (€/kWh)
  show: true
span:
  start: day
now:
  show: true
  label: Now
series:
  - entity: sensor.nordpool_energyprices_2
    color: green
    type: column
    show:
      extremas: true
    color_threshold:
      - value: 0
        color: lightgreen
      - value: 0.1
        color: green
      - value: 0.15
        color: yellow
      - value: 0.2
        color: orange
      - value: 0.25
        color: red
      - value: 0.3
        color: darkred
    float_precision: 3
    data_generator: |
      return entity.attributes.times.map((time, index) => {
        return [new Date(time).getTime(), entity.attributes.prices[index]];
      });
yaxis:
  - decimals: 2
    apex_config:
      tickAmount: 10

What am I doing wrong?
Many thanks!
