If you are having trouble entering TBD in your schedule, it may be due to another piece of software on your computer.
Please check to see if you have Comcast Constant Guard on your system. One of the install/uninstall options is "only let me input numbers in fields". If this is checked, your system will not let you enter TBD into our Korrio fields. Uncheck this parameter or uninstall Constant Guard to fix!
