ctrans might do it for you. Try something like this:

ctrans([F:PYH]BPANAM,","," ")

Nick Ward This worked beautifully my friend. Thank you! 

Curious if you know If there is a way to also take [F:PYH]AMTCUR and make sure it includes two decimal places?

You can use the format$ function:

Example format$('N0:8.2,[F:PYH]AMTCUR) will format the number with decimal places and padded with 0 in the front.

If you do not want 0 padding, then use format$('N:8.2,[F:PYH]AMTCUR)

The function link in online help is attached below.

Unfortunately this didn't work. I get this message when I try to save "Incorrect Expression, illegal character".
