This property is read-only; to assign a value type, use the SetValue(FormatConditionValueType) or SetValue(Double,FormatConditionValueType) methods.
Note that the unit of measure for this value is determined by the ValueType property; for example, when ValueType is set to Number, the value is interpreted as a numeric value, but when set to Percentage, it is interpreted as a percentage.
