Hi All, hoping you can help me here. I am a beginner and I am tring to access when a specific size more specifically if someone selects Custom Size as an option I want to an input field to appear.
I am access the following variable
{% assign current = product.selected_or_first_available_variant %}
{{ current.title }}
but this seems to be static. Can you please help me understand how I can check when the size value changes and access that?
