title: VBA excel #VALUE error
body: <p>I have a function that takes two string and it should add them.</p>
  
  <pre><code>Function teiseLopp(tekst1 As String, tekst2 As String) As String
      Dim stringidKoos As String
      stringidKoos = tekst1 &amp; "" &amp; tekst2
      teiseLopp = stringidKoos
  End Function
  </code></pre>
  
  <p>And it should return the two strings together but it shows me #VALUE! = Value used in the formula is of the wrong data type. (Everything seems to be right datatype)</p>
