Misplaced parenthesis in expression - visual-studio-2010

Question

Another pair of eyes to look at this would be great. I get one of two error messages the more I mess with this. Either it want's another parenthesis or that it's not a proper use of True/False. Im just getting a little frustrated looking at it. Any help would be much appreciated. It's been a long day.
=IIF((Sum(Fields!January.Value, "CDataSet")- Code.DivideBy(Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")) < 0
and (Sum(Fields!January.Value, "CDataSet")- Code.DivideBy(Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")))> Sum(Fields!Variance.Value, "CDataSet")),"Red",
IIF((Sum(Fields!January.Value,"CDataSet")- Code.DivideBy(Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2"))) > 0
and (Sum(Fields!January.Value, "CDataSet")- Code.DivideBy(Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2"))) > Sum(Fields!Variance.Value, "CDataSet")), "LimeGreen","Transparent")

Answer 1

When I indent the code to the levels of parentheses, I get:
=IIF(
(
Sum(Fields!January.Value, "CDataSet") - Code.DivideBy(
Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")
) < 0
and (
Sum(Fields!January.Value, "CDataSet") - Code.DivideBy(
Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")
)
) > Sum(Fields!ThresholdAging.Value, "CDataSet")
),
"Red",
IIF(
(
Sum(Fields!January.Value,"CDataSet") - Code.DivideBy(
Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")
)
) > 0
and (
Sum(Fields!January.Value, "CDataSet") - Code.DivideBy(
Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")
)
) > Sum(Fields!ThresholdAging.Value, "CDataSet")
),
"LimeGreen",
"Transparent"
)
Conclusion: The inner IIF has only one parameter, and the outer IIF has five. I think that you meant to put the two last strings in the inner IIF:
...
) > Sum(Fields!ThresholdAging.Value, "CDataSet"),
"LimeGreen",
"Transparent"
)
)
