Recipe: Ingredients * calculate portions

Hey Long, thank you very much for your answer.
But what do I do if I want to name my ingredients and specify the number of tomatoes, for example, that are calculated at the same time as the servings?

1x tomato * number of servings

If I define the field as a Number, I can no longer enter the name of the ingredient.

Hey Long,
I have now created a group

• Label: ingredient_group
• ID: ingredient_group
• Type: Group
• Cloneable: yes

In this group I have added 4 fields.

• Label: Number of ingredients
• ID: number_ingredients
• Type: number

• Label: Unit of measure
• ID: unit
• Type: Select Advanced
• Choises: l, ml, g, kg...

• Label: ingredient
• ID: ingredient
• Type: Text

• Label: calculation
• ID: calculation
• Type: number
• Read only: yes

Outside of the Group i have another Custom Field

• Label: portions
• ID: portions
• Type: Number

Im using the Oxygen Builder, so i added this Snippet to the Plugin "Code Snippets"

add_action ( '', function() {
    ?>
   <script type="text/javascript">
      jQuery(document).ready(function($) {
         $('body').on('keyup', '#portions, #number_ingredients', function() {
            var portions = $('#portions').val();
            var number_ingredients = $('#number_ingredients').val();
            var calculation = portions * number_ingredients;
         $('#calculation').val(calculation);
         });
      });
   </script>
<?php
    });

Unfortunately it does not work... What am I doing wrong?

Kind Regards and thanks for your Help!
