loTable.Columns.Add("Result_First_Accept", System.Type.GetType("System.String"), "IIF(Rej_Accept=2, ""REJECT"", IIF(MonPremacc.length=0), "" ""," + _ "IIF(Montestori = MonPremacc, ""SAME "", IIF(Montestori > MonPremacc, ""LOWER "", ""HIGHER""))))")Basically, the column I need to add is a calculated field but it is based on several conditions. One of them is the IIF() syntax which I don't think is supported. How can I adjust that, if possible?
