Access 2000 Query to use the larger of two numbers

I need to use the larger of two numbers in a calculation in my query.

Pseudo code would be like:

If Inventory_Qty > Order_Qty then
  ' Inventory_Qty - Components_needed = Surplus (below is the SQL)
  ([Inventory].[Quantity]-([Forms]![BOM_Queries]![txtBuilds]*[Qty per Asm])) AS Surplus)  
else
  'Order_Qty - Components_needed = Surplus
  ([Orders Subtable].[Quantity]-([Forms]![BOM_Queries]![txtBuilds]*[Qty per Asm])) AS Surplus)
end if

It has to be SQL as it is part of a Access 2000 Query.

Have you tried using an IIF statement;

this is where the test is in the first arguement, the result for true is in the second and the result for false is in the third,

ie Surplus: IIF(Inventory_Qty > Order_Qty, ([Inventory].[Quantity]-([Forms]![BOM_Queries]![txtBuilds]*[Qty per Asm]))),  ([Orders Subtable].[Quantity]-([Forms]![BOM_Queries]![txtBuilds]*[Qty per Asm]))))
