Thanks Paul,

The table is an idea I hadn't thought of, but I don't think it would work in this particular case.

Another issue is that there are input fields and tick boxes at various levels, and making a table to accommodate them all would be a nightmare.

I've found that there is horizontal band allocated for each line, and if I try to raise and/or lower text on one line to reach each element it only works until it starts to encroach on another line. Do you know a way around that? Could I put a merge field inside a borderless text box and move it into position by setting the text box properties to float above the text layer?
