Running a Potential Problems Report on a Legacy file can generate run-time error 3260 under certain conditions. Surnames entered as all UPPERCASE will in some instances trigger the error. Surnames in Initial Caps do not produce error 3260.
The solution is to click on Options on the menu bar and select Customize. Next click the 3. data format, then in the ‘Letter Case of Surnames’ area select ‘Initial Caps’ and click Apply and confirm the conversion. (If you want to show surnames in all CAPS, select ‘Show SURNAMES in upper case letters’ in the ‘Display Surnames’ area of the screen. Then click OK.)
In date fields, double prefixes such as "Born before 1853" or "Died after 1903" can also cause run-time error 3260.
The solution for the date problem is change them to single prefix dates such as “Before 1853” or “After 1903” from a Search List. Click on Search on the menu bar and select Find. Next click the Miscellaneous tab, then select 'All records with bad dates' and click Create List. Fix the bad dates.
