I have a need for a look-up table function in Excel.  The look-up functions
are combersome for my particular application.

I can create a table, for example prices, with several named rows and
columns.  I need to find values in the table based on imported data which
contains elements which would define which row and column a value would be
returned. For example, if my price table has prices for red, blue, and yellow
balls, of ten, twelve, and fifteen inch diameters and my input data is a
contains two columns that contain the color and diameter pairs, I would like
to use the values in the columns to fabricate a "=blue twelve" like command
that would extract the appropriate price from a table with those named
ranges.  

Thus far I have been forced to concatenate the values in the input data
columns with the appropriate equal sign and space for each of the rows, copy
the result to a word document, copy the word document content and paste it
back into the spreadsheet.  Excel thinks I have typed in that content and
happily finds the prices.  although it is a horrible thing to do 50 times a
month with different input data with thousands of rows.  It seems that since
Excel has the "=RowName ColumnName" function, one should be able to compute
the commands on the fly.

Any ideas on this?  I expect this is really a database function, but we
would like to accomplish it in Excel if possible.  

Thanks
