  When i run the script, i get an error 'incompatible types' then i run it a 2nd time, there is no error?
  What is causing the incompatible types ERROR?
  
  {Form has Edit1, Edit2, Memo1, Label4, Button
  }
  
  
  procedure TForm2.bRunClick(Sender: TObject);
  var
  a,b: integer;
  begin

  I have the same problem in my test application. I use the trial version for evaluation.
  I will not order the component if this error remains.
  
  Thanks

  I solved the problem. I read earlier posts from users encountered the same problem (what should be done before posting!!)!!
  
  The order of statements is important.
  
  This works:

    fsScript1->Clear();
    fsScript1->Parent = fsGlobalUnit(); // use standard classes and methods
    fsScript1->SyntaxType = "PascalScript";
    fsScript1->AddVariable("i", "Integer", i);
    fsScript1->Lines->Text = mCode->Lines->Text;
    if (fsScript1->Compile()) {
  	fsScript1->Execute();
    }
    else
  	ShowMessage(fsScript1->ErrorMsg);
  

  without error.
  
  This code:

    fsScript1->Clear();
    fsScript1->AddVariable("i", "Integer", i);
    fsScript1->Lines->Text = mCode->Lines->Text;
    fsScript1->Parent = fsGlobalUnit(); // use standard classes and methods
    fsScript1->SyntaxType = "PascalScript";
    if (fsScript1->Compile()) {
  	fsScript1->Execute();
    }
    else
  	ShowMessage(fsScript1->ErrorMsg);
  

  generated an error when the script was run the first time. Afterwards no error occurred.
