Crossing over different sheets

[Huggyd]

Is there away I can compare data from a number of different sheets and then show the lowest on sheet three.
For example: If I have prices from StoreA on sheet 1 and prices of the same items from StoreB on sheet 2 and again the same items from StoreC on sheet 3 and then what to display the lowest price from all the sheets on sheet 4 ... how do I accomplish this???
