I'm sure there's an easy answer to this....

How does one create a tool tip on a field, where the tool tip equals the value within the field?

For example:

Field Name: Hello

has a value of: How do you do?

If I highlight over this field, the tool tip will say "How do you do?"

I know it's something you add in the ControlTip Text field. I just can't remember the format....

Help!!!!
