Please help, this is my problem. Some formulas don't work when I type them in. For example, when I type this formula, it will say there is an error. "=SUM(1,2,3)" That does not work, it says invalid format. but if I do a formula with a range (instead of commas), it works. Such as "=SUM(A5:C5)" - that works just fine. I am guessing this has something to do with the commas in the formula. When I start to type a formula, a formula helper thing will be displayed that is showing the format of the formula. This format example does not include commas. It uses spaces instead. So I tried to type the formula with spaces (instead of commas) and that doesn't work either. I consider myself a advanced user of excel, I have extensive experience with excel formulas, so this is really bothering me (especially since I can't type many formulas because they need commas and that doesn't work). One more thing. I have existing spreadsheets that I am using (I have created these months ago). On these, I have formulas that contain commas and they all work. But if I double-click on the cell (as if I am going to edit the formula, but I don't edit it, I keep it the same) and press enter, the same error appears. If I hit escape, it cancels the formula edit request and goes back to how it was. I did try to uninstall and reinstall excel, that didn't work. But I think it is still pulling my info from somewhere. Thanks for all of your help.

Could this be related to regional settings? The comma is the decimal delimiter in most of Europe. On Tue, 14 Jul 2009 18:55:01 -0700, brandon_05mn <> wrote: >Please help, this is my problem.

Try it using a semicolon instead of comma: =SUM(1;2;3) Hope this helps. Pete On Jul 15, 2:55 am, brandon_05mn <> wrote: > Please help, this is my problem.

Hi, There is nothing wrong with the formula you showed us unless commas don't mean separaters. Try choosing Tools, Options, International, and checking to see what decimal separator and thousands separator you are using. You can uncheck Use system separators and then change the above options. These are related to your system settings. -- If this helps, please click the Yes button. Cheers, Shane Devenshire "brandon_05mn" wrote: > Please help, this is my problem.

Brandon Check your regional settings in Windows. It sounds like your culture setting have been changed. If its not that then check that Lotus compatibility has not been set for the affected sheets.

Neither Lotus 123 nor Lotus Symphony (the original, not the new OOo 1.x clone) were ever afflicted with space as argument separator. Have you really seen this behavior due to Lotus compatibility being activated and fixed by Lotus compatibility being deactivated?
