You need an object before you can call one of its methods. E.g. add to 
your form class
   MyFuncs: TSharedFunctions;
and create it in e.g. FormCreate:
   MyFuncs := TSharedFunctions1.Create;
Then use that object to call e.g. MyFuncs.DoSomething().

Or you forget about TSharedFunctions1 and make DoSomething a simple 
function.
