Hi
I have a multi page form with 4 pages - the last one is confirmation page used to print data entered / selected on page 1-3.
Page 3 contains the following checkbox:

On the confirmation page (page 4) I put the following to print the selected checkbox values:
1) When new session starts and you get to page 4 with confirmation the selected values are printed correctly e.g. 'ACS' checked prints:
Member of trade associations: ACS
2) When you press back and change the checkbox values it seems to work fine:
Member of trade associations: ACS, NFRN, SGF, RetailNI, Other/None
3) When you use the Back button again the problems start e.g. when only 'ACS' and 'Other/None' are checked I get the following values printed:
Member of trade associations: ACS, Other/None, SGF, RetailNI, Other/None
4) Now when I press Back and select only 'Other/None' I get the following print-out on the next page (confirmation):
Member of trade associations: Other/None, Other/None, SGF, RetailNI, Other/None
Something is obviously not right - the printed values are incorrect e.g. 'Other/None' is printed multiple times instead of just one in case no 4 and in case no 3 'ACS, Other/None' should be printed but I get 'ACS, Other/None, SGF, RetailNI, Other/None'.
How do I solve this?

On the confirmation page (page 4) I put the following to print the selected checkbox values:
<tr><td><strong>Member of trade associations: </strong></td><td>{data.join[, ]:select_trade_associations}</td></tr>This generally seems to work but I also have "Back" buttons on all pages.
