title: Conditional sumif for dynamically change range
body: <p>I want to use </p>
  
  <pre><code>=if((sumif(c1:c15,"ukw",b1:b15)&gt;=12),(sumif(cX:c15,"ukw",bX:b15)),(sumif(c1:c15,"ukw",b1:b15))
  </code></pre>
  
  <p>Now I want <code>X</code> in <code>cX</code> should automatically change to <code>C</code> cell  number which when added satisfied the condition <code>&gt;=12</code>.How to achieve it?</p>
