Change first letter in floating field to a capital letter

Still need assistance.  I would like to know how I can change the first letter in a floating field to a capital letter.  The floating field is tied to a text field and how ever the entry is made in the text field, I would like the result in the floating field to start with a capital letter.  Example:  If the user enter the word "apple" in a text field, I would like it to appear in the floating field as "Apple".  Any help would be appreciated.  My form is a livecycle designer form.
