#NAME? in the result

The formula uses a function that doesn't exist or a column reference that was typed by hand.

#NAME? means the formula contains a name General Caster doesn’t recognise:

• A misspelled function, for example SUMM(...) instead of SUM(...).
• A function that is not available. General Caster supports the common spreadsheet functions plus its own MONDAY.* functions.
• Two references next to each other without an operator. {pulse.a}{pulse.b} gives #NAME?. Join them with &, as in {pulse.a}&{pulse.b}, or with CONCATENATE.
• A reference typed by hand. See Referring to columns.
