Excel/force/control number/dashes format
I'm using MS Windows 7 Enterprise SP1 and MS Office 2010. I have a column of numbers using this format ##-8-#####-#. I tried custom formatting and conditional formatting without success. I need to keep the data entry user from entering any number that is longer or shorter. And the hyphens/dashes have to be exactly where they are. And the "8" in my example always has to be an 8. Thanks in advance for any help.
I'm slightly confused as you refer to numbers with a custom format, and then to dashes - IF the numbers ARE numbers with a standard format, then the only bit to check is the position of the 8. But I'm guessing you need the data entered as text - if so, using A2 as an example, you need to use data validation to fix this (data ribbon, then the data tools section) - enter this custom formula (I think I counted the length correctly but amend if not)
