I saved some modules into the same package or notebook which I call ModuleLibrary.m

I then get/call this package using Get[DirectoryPath\ModuleLibrary.m] in my actual analysis notebook.

However when I come to use some module, it doesn’t work. Mathematica behaves as though the called module is uninitialised E.g. If I go MyModule[Data] I just get the output MyModule[{{x1,y1},{x2,y2},{x3,y3}...}] rather than the actual result.

The modules themselves definitely work as I can use them inside the ModuleLibrary.m file itself, and they behave as expected.

The package itself is laid out as:

BeginPackage["MyPackageName`"]  Begin["`Private`"]; MyModule1[x,y]:=Module[Some code here...] End[];  Begin["`Private`"]; MyModule2[x,y]:=Module[Some code here...] End[];  Begin["`Private`"]; MyModule2[x,y]:=Module[Some code here...] End[];  EndPackage[];
