Please help a novice

I am using the cdate function to populate a number of
textboxes in a userform with date information. However
when the fields are empty cdate returns 00:00:00 into the
textbox.

Is their anyway to force the textbox to be blank rather
than 00:00:00 when no date exists.

I am self taught so please make any explanation dummy
prove:)

Many thanks
