[HELP] Error in Login Script

[HeK]

Is it because of the capital "I"? Theres a lot of logIn in this script, i didn't want to mess it up. Can anyone help me please?

This error appears when a player tries to register an account that is already registered.

Error:

Seems like 'account' is not returning an account userdata, but a boolean.

Try adding some debug outputs.
