I've been going through adding entries for cargo to the iFSO mod files and have run into a problem. For some reason it comes up:

Runtime error 9
subscript out of range

I've checked through the others and they don't share the same numbers. The problem ones are below:
2904938894 = commodity_destroyloot_JT03_duch_Mason, Destroy loot
2383317120 = commodity_target_JT03_duch_Mason, Target for long mission
2817289032 = courier_milldata_rh01_10, Courier Cargo
2920998472 = courier_troop_assign_rh01_10, Courier Cargo
2212560524 = courier_weapons_grade_explo_rh01_10, Courier Cargo
2998679744 = courier_defensive_weakness_rh01_10, Courier Cargo
3193683075 = courier_defense_plans_rh01_10, Courier Cargo
2714589263 = courier_battleship_specs_rh01_10, Courier Cargo
3073883975 = courier_killer_robots_rh01_10, Courier Cargo
2272280587 = courier_smuggled_secrets_rh01_10, Courier Cargo
2818132800 = courier_milldata_rh03_08, Courier Cargo
2920269376 = courier_troop_assign_rh03_08, Courier Cargo
2213928580 = courier_weapons_grade_explo_rh03_08, Courier Cargo
2997426376 = courier_defensive_weakness_rh03_08, Courier Cargo
3192822923 = courier_defense_plans_rh03_08, Courier Cargo
2715318343 = courier_battleship_specs_rh03_08, Courier Cargo
3072499535 = courier_killer_robots_rh03_08, Courier Cargo
2271567875 = courier_smuggled_secrets_rh03_08, Courier Cargo

Any ideas?
