I've a worksheet with some formulae referring to different cells on the same sheet, e.g. "= B52" shows the name in b52(avoids entering a persons name twice). Most of the cells work fine, and have done so for months. A few however insist on seeing the formula as text and show only the formula, not the result. This just popped up, I have no idea what has changed in those few cells. Anyone have any ideas?
