need a solution for repeated error message in RC

[khortez]

i was trying to create a gui window but for some reason i keep getting this error message: "Script: Function addcontrol not found " can someone tell me a solution for that?



edit: i don't think it's the code but if necessary, i'll provide it

editx2 : i still don't have a clue of why it was acting the way it did.. so if anyone wants to give me possible reasons for why it was saying that i would be grateful so i could fix it/prevent it in the future. though it's fine now
