what does "you can only type in a text box, table mean?

[LA]

I can't type on the calendar that I made, the message that comes up says,
"you can only type in a text box, table, and certain shapes". I could type
in it yesterday, so I don't understand! Please help!

This emssage appears when you don't have an object selected into which to
type.
You need to select a text box or a table, or create a new text box, in order
to type.
