title: Function for getting a specific sheetname
body: <p>I have a workbook with the following apperance:</p>
  
  <p><img src="https://i.stack.imgur.com/IKTVm.gif" alt="enter image description here"></p>
  
  <p>This workbooks first sheet, "Resultat", calculates data from the other sheets in the workbook and presents them as the picture shows.</p>
  
  <p>In order for the calculations to work correctly, the names shown in the marked red squares must be the same and corresponding, else the value will be ##### as you can see for entry number 2 (cell A5 works and have the same name as sheet number 2, but cell A8 do not work because it does not have the same name as sheet number 3).</p>
  
  <p>My question is basicly, is it possible to use a function that will enter the name of a sheet in a specific cell. In this example, I would like the <code>cell A5</code> automaticly fetch the name of the sheet with <code>index 2</code>, <code>cell A8</code> be equal to sheet with <code>index 3</code> and so on. </p>
  
  <p>Right now im doing this manually but it would be a great help if this could be automated since I have alot of these workbooks and the names changes from time to time. </p>
