Link text in the Comments field of the Calendar File (or any other Memo type field) will be clickable if it is in the correct format. Include the full URL, starting with “http:”, “https:”, or “www.” with the link text.
Alternatively, you can add a Web Page type field to the Calendar File to store these links. This field type allows you to add a clickable link to the calendar.
To add a Web Page field to the Calendar File
You can now add the new field to the Calendar file via Form Designer. Form Designer can be accessed while on the List tab of any file via Edit | Form Designer.
