Hi Jamal,

Please see this thread.  What you want to use is called Dot Notation.  At 10 this functionality does not exist any longer (although there is an enhancement request to bring this back).  What you can do it using the Lookup tool, to create 2 new rasters based on your fields, then multiply these together.
