Reporting Services :: Colour Formatting Based On Conditions

I have an issue in trying to format rows base on conditions. Below is a replication of the tables and the select statement.

CREATE TABLE #CompareVal
(CompareValID INT Not Null
, ValName NVARCHAR(75) Null
, Vehicle INT Null
, Driver INT Null
);
GO

[Code] ....

First issue, James and Jane does not have a driver available and that should show "No Driver available"I am to compare values in VehicleAvailable and DriverAvailable to the first row - (Group Value Standard row) so that when a value is less than the value in first row, it should be Gold, if equal to, Blue and if greater than then, Red.

The first row is to be Black. In other for me to be able to compare, I added columns like so:

SELECT #CompanyName
, [Description]
, ISNULL(CAST(VehicleAvalible AS NVARCHAR(30)),'N/A') AS VehicleAvalible
, ISNULL(CAST(DriverAvailable AS NVARCHAR(30)),'No Driver available') AS DriverAvailable
, 0 AS TotalVehicles
, 0 AS TotalDrivers

[Code] ...

And my expression for "VehicleAvailable" column is :

=Switch(Fields!Description.Value = "Group Value Standard" AND Fields!VehicleAvalible.Value = Fields!TotalVehicles.Value, "Black"
, Fields!Description.Value = "Group Value Standard" AND Fields!VehicleAvalible.Value < Fields!TotalVehicles.Value, "Black"
, Fields!Description.Value = "Group Value Standard" AND Fields!VehicleAvalible.Value > Fields!TotalVehicles.Value, "Black"

[Code]....

This doesn't work as I am comparing integer against text value. How do I format to get result like the below image?
