Hello Jane,
yes, I discommented it.
If I place your transparent textbox in the header,
the table in the body does not move at all, in both cases (with or without the transparent textbox):
with vertical position 35, the tblCorse table is too far from the header,
with vertical position 34 (I wrote badly in my previous message, excuse me),
the tblCorse table is overwritten in the header.
I wait for you answer,
thank you,
Paola
