Only some of the lists work and I can't for the life of me work out why,
the lists have exactly the same numbers in them.
so *202, *502, *702, *802, *902 work the others dont.

this is the contents of the ListX.txt file

02,7811,some data,,append
03,7811
04,7811,,,,

any pointers would be gratefully received.
