URGENT - Tier 1 General Dependant - Online form help needed

URGENT HELP NEEDED Please :

I will be applying for my wife's dependant visa very soon. Category - Tier 1 General Dependent. However the online form seems to be confusing to us.

My wife will apply through her login details:

Passport/travel document - Her details which also includes name/dob details
Personal details/travel history - her details again
Family history - they are asking for spouse/partner details (which will be mine)
Medical treatment - her details
Maintenance - relevent info
MAIN APPLICANT - this where the confusion is. they are asking for name/dob/passport details. now whose details do we have to enter. Am i going to be the main applicant or my wife . if its me (main applicant) then do we have enter my same details again which we have entered under family history (spouse details) , it seems mostly likely the details must need to be repeated but we are not sure whose details we have to enter

PLEASE REPLY URGENTLY BECAUSE WE WILL BE APPLYING ON 17-8-2014.

People who have recently applied can be massive source of help.

Urgent response is much appreciated.

Many ThankS
