You have to recall the function to the stack before you perform the command MAP. Let's say you have a list saved as MYLST and a function saves as MYFCT, then from the VAR menu press MYLST to put the list in the stack then then 'MYFCT' enclosed with single quotation marks, then press [left-shift][STO] to RCL the content of MYFCT, now you are ready to use MAP.
