Clarification reg.VAF/GWF in ILR application

My husband is holding UK Settlement (ILR) through Tier 2 General 5 Years route - granted in Aug this year. I and my kid (India born) are in PBS Dependant visa. PBS dependant Visa issued Date 14th Sept 2014. I am applying ILR application for myself and our kid. Can you please help me to answer the below questions in application form ?

1) Which visa is Mr xxxx applying for or been granted? (Please confirm I assume I need to provide T2 General route)

T2 General

2) Do you have one of these reference numbers for Mr xxxxxx? ( I am not sure about the below reference number, can you please help?

Yes, I have their VAF number

Yes, I have their GWF number

No, I do not have a reference number for them

Where can I get a VAF or GWF number, I have already provided the HO reference i.e. Case id and BRP number in the application. I think VAF is my husband’s application number (16 digit numeric code) but I am not sure.

Please can you help with these queries?
Thanks in Advance

T2 general is good. Ignore the reference question no need for VAF or other references
