highlight only formula
 

hi, i am having 2 worksheets, In worksheet 1 some cell have formula but it is
calculation depends upon Worksheet 2, so i want to hightlight the changes at
Worksheet1 at those cells, where formula is change depend upon the change in
Worksheet2.

Eg.

Worksheet1
Code-Product-Qty
x-xyz-50
y-xyz-100

Formula for

Qty:Vlookup(Index,match(<cellref,<range,False),3 )

Worksheet2:
Code-QTY-PRICE (Where Qty,and price are changeble but code is fixed)

x-50-1000
y-100-2000

Now suppose, for the Code= Y, i changed the Qty=50, then it should only
hightlight the formula for the Code Y



Thanx
