If you cannot paste data into one of the option B forms, try “disabling” macros when you open up the form. Be aware that none of the software features will work when you “disable” the macros. After you paste in the data, save the form and close the software. The next time you open the form be sure to “enable” macros.
Note: We have not observed this behavior in recent versions of the Option B workbooks. If you are using the Excel workbooks distributed with Option B version 6 or later and have this problem, please contact us so we can investigate the issue.
