SUM(MAXNUM(...)) not working in script

[AKCarlow]

In a Memo text on a MasterFooter band, this works:

[SUM(MAXNUM([qPrintBills."Fixed"],[qPrintBills."Fixed"]+[qPrintBills."Charge"]),MasterData1,1)]

In a Memo script on a MasterFooter band, this doesn't:

TheData := SUM(MAXNUM([qPrintBills."Fixed"],[qPrintBills."Fixed"]+[qPrintBills."Charge"]),MasterData1,1);

neither does this:

TheData := SUM([qPrintBills."Fixed"]+[qPrintBills."Charge"],MasterData1,1);

Should SUM work in a script?

In the script, a space is need either side of the + to make it work!
