Special method to modding buildings?

[Dahak]

I am trying to make Roman military buildings cost upkeep rather than food, yet for some reason it tells me my mod is conflicting with another mod (even when mine is the only one activated).

Is there some trick to doing this in Attila? I am used to modding Rome II and Shogun II but this is my first Attila mod.

I copied the method used in the Grand Campaign 2.0 mod on the Steam Workshop (which works fine, I just don't want all it does and I want this only for Rome).

I am modifying building_effects_junctions by deleting the food use line while keeping everything else in the table the same.
I am modifying the building_levels by adding upkeep cost to the roman military buildings in a new table with a different name.

Well I figured it out. I somehow managed to put a space in the file name at the very beginning. Whups.
