Hi Tom
Thanks for the version to cope with my file. Its worked (JCloze2 marker appeared). Hurrah! 
I also had to clear the cache as suggested. I have sent an email reply but I'm not on the right ISP connection here to be able to send reply just yet. It will go tonight when I get home.
Thanks again
BTW I wonder if all my HotPot modules have bits missing. I am using version 5.5 ..... HEY I've just thought of something. 
There is a version 6 preview in the potatoes and I have been using that for output... THAT may be why your original hotpot converter couldn't find the usual string. It says in the HP help files that version 6 will be different. Does that help? 
I've now download version 6.0.3 of Hot Potatoes and its output files are not working 
. I'll attach the example file which has been changed. BTW the JCloze2 marker didn't appear this time.
