Bug in the call 
I think it is a design flaw in the CheFare call itself. They don’t ask for a budget, so you don’t feel compelled to do one when you “focus on the call”. But this is a mistake: a budget is a great tool for figuring out what needs done, who can do it, what resources it needs, what priorities are involved. No budget, no project. I have said so many times in the course of the application process.
What the evaluator told you, however, might solve the problem. Not having explained what we need the money for is likely to get the project disqualified – so we don’t even go to the next stage, and that’s the end of that.
