Hey all, I hope you can help me

I have now spent several hours trying to figure this out(new to modding) but it never works. I am trying to add a good pike unit to Cyrenaica but it never shows up in custom or in the campaign.

Please tell me what I am doing wrong, this is what I am doing I am using PFM 3.1.8:

- First thing I do is I make a new mod under my mods

- Then I add Buildings_units_allowed and units_to_groupings_military_permission to my mod from rome2_data.

- Now I delete most of the stuff in Buildings_units_allowed and units_to_groupings_military_permission I keep 2 lines in buildings and one in units where I change it to Gre_Thorax_pike to be rectuiable by ptolemaic_cyrenaica on the rom_HELLENIC_military_main_heavy_3 and 4 wich it is already set to but I keep it there just in case.

- I then install, make sure it is selected in mod manager and play the game. But it just startes up without any changes to cyrenaica.

What am I doing wrong?
