New Bug Encountered: Blank screen with EXTRACT() and -LIST("")

[Fabian_Weller]

DECIMAL(INDEX(EXTRACTPRICES([OCRTEXT]),6))
is working fine
DECIMAL(INDEX(EXTRACTPRICES([OCRTEXT])-LIST(""),6))
is producing a blank screen in the form when you add a new row.

My goal is to remove prices with no value. I can’t use UNIQUE(), because I don’t want to remove duplicates.
