title: Matching the 1st satisfying inequality with 1 criteria & getting the column title
body: <p><img src="https://i.stack.imgur.com/uB6Uy.jpg" alt="enter image description here"></p>
  
  <p>What I need is </p>
  
  <ol>
  <li><code>B</code> column values (red) should be calculated by Excel without VBA</li>
  <li><code>A</code> column (<code>Conf. Level</code>) has the criteria values per row</li>
  <li>In each row, <code>B</code> column's related cell must print the 1st same row cell's column title that is >= than related criteria value</li>
  </ol>
  
  <p>For example: </p>
  
  <blockquote>
    <p>B2 prints 0 since C2 is the 1st value that is >= than A2</p>
    
    <p>B3 prints 2 since E3 is the 1st value that is >= than A3</p>

  <p>I've read the Q&amp;A in this site with excel, indexing, match tags and tried something but I couldn't achieve more than #N/A. I've also read Microsoft excel help pages for <code>Index()</code> and <code>Match()</code> functions.</p>
  
  <p>I have tons of rows in real case (not only 3 data rows).</p>
