Worksheet Functions

=FDS() 
=FDS("EURPLN","FG_PRICE(45348)") 

This function is case sensitive though and will not work if entered as "=fds()"
There is a bug in Excel worksheets that saves the case of the function, the first time you enter a function name.
If the first time you use this function, you type it manually in lowercase, the function will never work correctly in that worksheet.
