Writing into Range.FormulaArray gives me a #NAME! error

Question

Nothing really fancy here, altough I need to split the formula in 2 because it is longer than 255 characters (sources: http://www.dicks-blog.com/archives/2005/01/10/entering

Answer 1

Because Excel has .Formula for formulas in English and .FormulaLocal for formulas in the language of the Excel interface.

You need the local version, but there isn't one for arrays. You have to provide array formulas in English.

You could e.g. set this French formula to .FormulaLocal of a temporary (hidden) range, then read back .Formula from the same range and set that as .FormulaArray on the desired range. But you shouldn't, because your code won't work on any Excel version other than French. The most portable thing is to always use English formulas in your code.
