When posting code to the forum, please use code fences instead of blockquotes. See:

The outer range is scoped to .Params.app_monthly_plans
. That means your inner range is trying to iterate through .Params.app_monthly_plans.Params.app_feature_data
, which doesn’t exist. Please read:
https://regisphilibert.com/blog/2018/02/hugo-the-scope-the-context-and-the-dot/
Instead of this:
{{range $index, $plan_feature := .Params.app_feature_data}}
Do this:
{{range $index, $plan_feature := $.Params.app_feature_data}}
Also, in the page’s frontmatter, make sure app_feature_data
is defined before [[app_monthly_plans]]
.
