I'm stumped on my find/count routine

[Björnke von Gierke]

I did not test your search, but it is there are some things you could 
check into to make your script work. (see below)

additional needed for clearing your search to not start searching where 
the last one stopped:

it is possible that cVar is not on the first line,
thus x =1 does not match the number of lines already gone by

why do you first search for one instance, and then for the rest?
wouldn't it be easier to just search each line without verifying a 
first occurrence?

you sure this shouldn't be "next repeat" ?
also the search starts where it last left of, so foundLine should not 
be able to equal y

maybe it is one of these things that gives you strange results?
