Hi guyKn,
What exactly wants to change - I presume it's both the amount (based on an exchange rate) and the currency symbol? You might consider this approach ..
Somewhere out of the way, let's say in columns
AA,AB,AC for now, have a table of exchange rates and currency symbols ..
Cell AA1: "Dollars"
Cell AB1: Exchange rate multiplier (base units to dollars)
Cell AC1: The dollar currency symbol
Cell AA2: "Pounds"
Cell AB2: Exchange rate multiplier (base units to pounds)
Cell AC2: The pound currency symbol
Cell AA3: "Euros"
Cell AB3: Exchange rate multiplier (base units to euros)
Cell AC3: The euro currency symbol
Somewhere else, for now let's say
Z1, have your single value that you want the formatting to be dependent upon.
Now, with a base values in column A starting in A1, put the following in cell B1 ..
[blue][tt]=TEXT(A1*VLOOKUP(Z1,AA1:AC3,2,0),"[$"&VLOOKUP(Z1,AA1:AC3,3,0)&"0.00")[/tt][/blue]
.. and copy B1 down as far as your values in column A go.
Now, if you put "Dollars" in cell Z1, values in column B will be formatted in dollars; if you put "Euros" in Z1, values in column B will be formatted in euros, etc.
Enjoy,
Tony
