Fatal error please help!

[plantum]

you're line """"void SetLevelDoorLocked(string& asName, bool abLocked)""""
is incorrect. you should change it to
void unlock_level_hub_1(string& asName, bool abLocked)

[EDIT]
the reason why its wrong (incase you are a learning type) is because you have the callback function at the beginning
void Onstart
{
AddUseItemCallback("", "key_tower_1", "level_hub_1", "unlock_level_hub_1", true);
}

isn't referenced correctly, so change it to what I put above and it should all smoothen out

Don't thank me, BLOW ME

Now i get this error:

Change "SetLevelDoorLocked("level_hub_1", false, true);"

to "SetLevelDoorLocked("level_hub_1", false);"
