Thank you so much for the help.
As i validated the form i encountered error on question #3 (HOW MANY FAMILY MEMBERS, INCLUDING YOU, ARE IN THIS APPLICATION?) it says: "number of family members does not match on the application." I answered 3 (my wife---the principal sponsor, me and my daughter).
I figured it out that it may be because only me and my daughter are on the application, meaning only 2 family member appeared on the form.
my followup question is this.
Am I going to change the number of family members i answered from 3 to 2 on my form and change to 1 on my daughters form? or should i include my wife on the list?
