Error: Missing Method In ModuleScript

[CadenDevelops (Caden)]

Hello there,

I am currently in the process of making a grid-based placement system, and have run into an interesting error. Any help would be greatly appreciated!

Error:

  20:00:40.946  Players.CadenDevelops.PlayerGui.BuildMode.PlacementSystemV2:18: attempt to call missing method 'activate' of table  -  Client - PlacementSystemV2:18

Thank you in advance!

I could not find an :activate in the documentation.

What is this line:

function placement:activate(id,pObjs,plt,stk)

It seems to be the problem.

[CadenDevelops (Caden)]

That is supposed to be a function that I can invoke form the client script. If I was to change it to placement.Activate(), would that work?

For anyone reading this thread in the future, i solved this issue by adding the following line below the definition of the placement module.

placement.__index = placement
