--- Comment #13 from ady <adylo811...@gmail.com> --- I'm not sure the problem has something to do with un-matching brackets. The problem seems more related to either "uncommon" characters in named ranges and in the worksheet name (which perhaps used to have a space or some other special character in its name?), or related to formulas depending on named ranges. Every cell showing Err:508 depends on a named range. Note that cell B2 is named Taux and it has no error. Note that cell B1 is named Montant_du_prĂȘt and it has no error. Neither of these depend on other named ranges. In contrast, B4 is named MensualitĂ© and depends on Taux. B7 depends on it, and B9 depends on B7. The range B12:E12 also depend on these named ranges. Then B13:E13 and down are just a drag copy of B12:E12. Once you solve the "errors" in B4 and B12:D12 (by re-typing the last character in each), the rest is OK. Re-saving at that point solves the problem for the next time you open the file. I don't really know what these named ranges (or the names themselves) have so special that trigger this problem. If this hunch is relevant, the title/subject of this bug report should be modified, because unmatched brackets seems not to be the issue, but rather some kind of importing problem from xls regarding named ranges (and/or special characters in worksheet names?). -- You are receiving this mail because: You are the assignee for the bug.
