Sole Trader & Employed Confusion

Hi, I am in the process of setting up my start-up as a sole trader. As, like many people, I am working a full time job in conjunction with starting up my company I am a little stuck with how to instruct this on my application. Under "Are you working for one person or firm only?" would I need to put Yes? As I am still employed by a company as a full-time worker, even though it is not related to my own start up business? I am just a little confused and don't want to get this wrong! any help that you can give would be appreciated!

Hi
This question relates to your self employment status and not your PAYE employment.
As working for yourself answer yes.
