How to place button inside window same place

Hi.
I made a function called “OptionsWindow” Inside this I have a toolbar on the top.
if the toolbarInt is 0 it shows the audio settings, if it’s 2, it shows the Graphic settings etc. I have a Back button on each “page” but it’s on a different position depending on which toolbarInt is chosen.
How can I make the Back button stay on the same position all the time?

This is the code I use for the Back button

if(GUILayout.Button("Back", GUILayout.Height(buttonHeight)))
			{
				Debug.Log("Back");
				audio.PlayOneShot(clickSound);
				showOptionsWindow = false;
				showMainMenuWindow = true;
			}

Thanks

You can make a GUI control’s position set by using

GUI.Button

rather than GUILayout. Here is the scripting reference for this: Scripting Reference
