GUI Note taking box

Hey there! :)

Long story short, I have a project for school where I have to create a game, In the game I want to create a note taking box where people that play the game can take notes while they play the game. I've created so far a box where you can type something into it, but the problem s that I want to be able to resize it and drag it around on the screen

Here is the code that I've created so far:

 var stringToEdit : String = "Notes Here";
 
 function OnGUI () {
     // Make a multiline text area that modifies stringToEdit.
     stringToEdit = GUI.TextArea (Rect (10, 10, 200, 100), stringToEdit, 200);
     stringToEdit = GUI.Window (0, String, DoMyWindow, "My Window");
 }
 
 // Make the contents of the window
 function DoMyWindow (windowID : int) {
     // Make a very long rect that is 20 pixels tall. 
     // This will make the window be resizable by the top
     // title bar - no matter how wide it gets.
     GUI.DragWindow (Rect (0,0, 10000, 20));
 }

This is the code that i'm using but it just won't work :(

Any help would be so appreciated,

thank you!
