how to add a new unit to campaign?

hi i just recently made my own unit with my own textures "Royal Musketeers" and i made it work in the custom battle map. Now the problem is i couldnt be able to make it recruitable in the campaign. in the export_descr unit i set the ownership to england and also put it available in era 0, era 1, era 2 for england. and in the export_descr_buildings i put this "recruit_pool "Royal Musketeers" 0 0.000001 0.999 0 requires factions { england, }" right above the "recruit_pool "Peasants" 0 0.000001 0.999 0 requires factions { england, france, hre, denmark, spain, portugal, milan, venice, papal_states, Normans, Saxons, }" line. now can any1 tell me what am i forgetting to do?:stupido2: my unit just wouldn't show up recruitable in the campaign. i mean it works with the "create_unit" cheat but i just want to set it recruitable in the grand campaign "england" could any1 help?:help:

:laugh4: hehehe. nvm figured it out :idea2:

Just for anyone else who might read this, you need to add the unit to every building level for the building type you want to produce them from :)
