pyparsing trouble accessing ParseResults

I have a ParseResults object, which looks like this when I dump it: 

[[['FM4', '230', '30', '680']]]   
[0]:   
     [['FM4', '230', '30', '680']]   
     [0]:   
       ['FM4', '230', '30', '680']   
       - FormNumber: 'FM4'   
       - BookNum: '680'   
       - PageNum: '230'   
       - BookmarkNum: '30'

I can't seem to access the results by the name.

For example: results.FormNumber
Or, 

for i in results:   
    print("i dict", dict(i))   

results in:   
        ('i dict', {})

If I print :

print("i list", list(i))

I get :

('i list', [(['FM4', '230', '30', '680'], {'BookmarkNum': ['30'], 'BookNum': 
['680'], FormNumber: ['FM4'], 'PageNum': ['230']})])

How can I access the dictionary object by name? Thanks in advance

Upon further review of my grammar, I realized I was using a Group, which resulted in creating a list and not a dictionary.

After removing the group, this: ('i list', [(['FM4', '230', '30', '680'], {'BookmarkNum': ['30'], 'BookNum': ['680'], FormNumber: ['FM4'], 'PageNum': ['230']})])

Becomes this: ('i list', [(['FM4', '230', '30', '680'], {'BookmarkNum': '30', 'BookNum': '680', FormNumber: 'FM4', 'PageNum': '230'})])

And, then I was able to use the dictionary by name

Thanks
