Getting odd error from descr_strat

[Burns]

Im in the process of converting a map from 1.2 (if thats a hint to the problem). I've already applied the HGT Converter to it (so height shouldnt be a problem, I hope). However the error I am recieving is "Expected start date of campaign or battle" Im not quite sure what is wrong.

campaign		my_campaign
playable
	huns		;
	goths		
	vandals		
	franks		
	saxons		
	alemanni	
	sassanids	
	empire_east	
	empire_west	
end
unlockable
end
nonplayable
	sarmations		
	empire_east_rebels	
	empire_west_rebels	
	ostrogoths
	slave
end

start_date	2954 summer
end_date	3054 summer

so hmm, not sure why thats being reported as the problem. I wont know what other problems are there if this error doesnt stop showing.
