    decimal ActualFTE=Convert.ToDecimal(e.Row.Cells[5].Text);
    if (ActualFTE > 1.25)

    In the above code check whether e.Row.Cells[5].Text returns data that can be converted to decimal. Or add ToString() at the end and see if it helps.

    decimal ActualFTE=Convert.ToDecimal(e.Row.Cells[5].Text.ToString());

      Just to make sure everything is fine, try hardcoding the value and see if you still get the error.

      decimal ActualFTE=Convert.ToDecimal("0.9500");

      If this works without exception, then you can be sure, the problem is with the expression e.Row.Cells[5].Text. This expression you use should return some string (like your value 0.9500) that can be converted to decimal for the conversion to work without exception.

          May be the value ActualFTE is not greater than 1.25, as per your condition.

             if (ActualFTE > 1.25)
             {
                e.Row.BackColor = Color.Red;
              }
          

          So the color will not be changed.

            That is true for most of the 251 rows. I only see a couple that are over 1.25. So I should take out that code?

              Do you think I should post all of my code to see if I have something missing?

                When you want the row to be colored? Change the if condition based on that. It should work.

                      Mathi, I was able to get it to work. Thank you for your help and patience. You and others have help me to complete this project.

                      protected void gvCATW_RowDataBound(object sender, GridViewRowEventArgs e)

                      {
                      if (e.Row.RowType == DataControlRowType.DataRow)
                      {

                      // To check condition on integer value
                      if (Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "ActualFTE")) > 1.25M)
                      {
                        e.Row.BackColor = System.Drawing.Color.Red;
                      }
                      

                      }
