Being most scatty, gets confused about identity one way and another (8)

'being most scatty' is the definition.
(giddy can mean scatty or excited)

'confused about identity one way and another' is the wordplay.
I cannot quite understand how this works, but
'identity' could be 'id' (abbreviation) and 'id' is found in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
'way' could be 'st' (abbreviation for street) and 'st' is found in the answer.
'another' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
This explanation may well be incorrect...

'gets' acts as a link.
