title: SSRS Change cell color depending on SUM value
body: <p>I am loading a dataset into my report and filling my last column with this expression: =Sum(Fields!ID.Value) and it loads fine, I am trying to put a condition in so when the number is less than 15 for example, the cell color will change to red. I have tried so many different syntax but nothing works... it must be pretty simple...?
  The errors I am getting are: The value expression for textbox has scope parameter that is invalid for aggregate</p>
  
  <p>Any help would be good :)</p>
