Ok, I tried below, past error has gone, but now I am getting error in Demographics form (main form):
[Error] Demographics.pas(50): This form of method call only allowed for class methods


unit stringcheck;
interface
type
    TSharedFunctions1 = class
    private
    { Private declarations }
    public
      function DoSomething: string;
    end;
implementation
       {$R *.RES}
uses sysutils ,StrUtils;
_____________
Demographics form (main form):

procedure TForm2.Button1Click(Sender: TObject);
begin
  ShowMessage('tetss-'+ TSharedFunctions1.DoSomething());  //getting error This form of method call only allowed for class methods
end;
