I want to make a form with a group x that contains within it another group x, but the inner group isn't showing up.

I've been given a salon menu structured like so...

Our Services:

Hair Care

Long Haircut - $10.00 & Up

Shampoo Set or Blow-dry Curl/Iron - $8.00

Etc...

Skin Care

Plain Facial No Make-Up - $15.00

Eyebrow Tweeze - $6.00

Etc...

I want to make this as easy as possible for the client to add, edit and remove items from this menu page.

Here's what I came up with:

[Title] Our Services 

[GroupX1 with 2 fields]

{ Field 1 - Service Type: [Text] }

ex: Hair Care

{ Field 2 - Service Info: [GroupX2 with 3 fields] 

Field 1 -Name

Field 2 - Price

Field 3 - Unit }

ex: Long Haircut - $10.00 & Up

[Submit]

This way they can add new sections (GroupX1) and within those sections add new line items (GroupX2). It seemed like a natural use, so I was surprised when GroupX2 didn't show up. I have the internal fields set to store none, while the group x fields are set to store "Custom - Article - Introtext"... So what am I missing?
