title: Hide/Unhide groups of cells in excel with Button
body: <p>I have a group of cells B32 till R32 length and B32 to B51 breadth. I want to keep this block hidden at the start when the sheet is opened. I have named this block as 'Analysis'.</p>
  
  <p>There is a button in the sheet. When the button is pressed, I want to unhide that block. I am new to Excel Vba. I would like to know the syntax/code for doing this operation.</p>
  
  <p>Thanks in advance.</p>
