I would use the ISNA() function to determine if the value looked up does not
exist and if not place a zero. If the lookup returns a N/A (N/A= not
available) then it laces a zero, otherwise the if goes ahead and does the
lookup and returns the value.

Something like this:
=IF(ISNA(VLOOKUP(C11,'Payment
Matrix'!B128:C134,2,TRUE)),0,VLOOKUP(C11,'Payment Matrix'!B128:C134,2,TRUE))

Hope that helps.

Here's the formula: =VLOOKUP(C11,'Payment Matrix'!B128:C134,2,TRUE)
