title: USERFORM Function Error
body: <p>I've been trying to create a simple USERFORM function. My requirement is to basically compute add, multiply, divide, and minus mathematical functions. However I had difficulties, when I run ADD function, say I add 5 plus 5 then it comes out 55 instead of 10.</p>
  
  <p>Example as below</p>
  
  <pre><code>A Value = 5
  B Value = 5
  Result  = 55
  </code></pre>
  
  <p>It shouldn't be 55.</p>
