Scheduled Transaction formula support string literal parameters.

[Derek Atkins]

Hi,

Unfortunately this is a naive approach to this; Account names can (and
do) change.  You really need to use the internal Account GUID in the SX
storage.  But of course you want the user to be able to use the Account
Name.  So really what you need here is an input UI that lets the user
input the account name, but then internally it gets translated into the
account GUID..  For this I would almost recommend a "Function Editor"
popup dialog to help.

It's so much more complicated than what you have.  :(

Moreover, you need the *date* in there, because you really want to be
able to call xaccAccountGetBalanceAsOfDate() in the SX, because the SX
is run at a particular date that may be in the past.

Good Luck!
