Applying visa for sister and minor...its urgent..

[Maxka]

Hello...i m applying 6 months visit visa for my sister and her minor children...i have completed the form but the problem is what should i write in minors application form for saving and income? Do i need to fill that up with parents income and savings? Its asking about the monthly bills so how can i write about that in minor applications? If i dont write then its not going through the next part... its asking about monthly expenses as well..so what should i write? Should i write the same things i wrote in my sisters application?
