Here is an easy and elegant way - almost what you started with!
The key is 'of' versus 'in'. They are not quite the same.
Try this - tested Win/Mac, LC 9.6:
if there is a field "xyz" of group "abc" of this card then answer "xyz"
put there is a field "xyz" of group "abc" of this card & cr after t
For objects/controls, 'of' is the correct syntax.
But 'in' is mainly used for text. Not a safe substitute here!
(The Message Box may just ignore everything after 'in' -
testing only for a field "xyz". That can confuse about 'of' and 'in'.)
The Script Editor will actually error, since 'in' is unexpected.
Happy coding...
