Just learning how to put ELF in reports and following the examples. I successfully created the NumberToWords function. However, when I added the FileExists function as in the example, I get an error: "Error -119, Can't load function FileExists. I also added another function just like the NumberToWords but for currencies "CurrencyToWords" where I copied the NumberToWords and just added "Dollars and Cents" to the return and I get the same error! What am I doing wrong?
