Sivakatirswami-

Well, your tCompleted also remains constant - it's just the ratio of
download locations that changes. Which makes sense, since what you're
displaying is

line 1: tRevHits
line 2: tCompleted - tRevHits

Also, are you really saying put ("1"&quote&"200 ") into tCompleteCode?
Shouldn't that be put ("1"&quote&&"200") into tCompleteCode?
>From your output it looks like you're trying to trap the (1.1" 200)
string, which has a space *before* the 200. Same thing for the 206.

You don't say where the mouseUp handler is located, but since you're
not initializing your variables to zero before running, could there be
some leftover garbage in there from the previous run?
Mark. Thanks for the pointers. It works now, but I have to wonder as there is some serious gremlin hiding here:
1) I thought local variables are always initialized to empty after each run of script. 
Is there something I'm missing there?

global tStart
local tPartials,tRevHits,tCompleted # these were acting as globals?

2) OK we know that
if x contains "Hinduism-Today_Jul-Aug-Sep_2009.pdf" then put x & cr after tFoundLInes 
       end if

works, consistently thru each run because it returns 4405 GET requests for the 
PDF on each run of the script.

*BUT*

if the string

1"&quote&&"200"

does not even exist in those 4405 found lines how is any number returned at all?
if x contains "Hinduism-Today_Jul-Aug-Sep_2009.pdf" then put x into z 
        if z contains "Revolution" then add 1 to tRevHits
        put  ("1.1"&quote&"200 ") into tCompleteCode
        put  ("1.1"&quote&"206 ") into tPartialCode
        if z contains tCompleteCode then add 1 to tCompleted # should not 
increment
        if z contains tPartialCode then add 1 to tPartials # should not 
increment
        put empty into z
        put x & cr after tFoundLInes
     end if

but we get:
Summary: Downloaded with Revolution HT Navigator: 834 
Complete Downloads via HT site: 1488 # should be 0
Partial Downloads 206's (mostly failures, some successes): 6801 # should be 0

3) I took your suggestions initialized the vars and fixed the string.



on mouseUp
  put 0 into tPartials
  put 0 into tRevHits
  put 0 into tCompleted
if x contains "Hinduism-Today_Jul-Aug-Sep_2009.pdf" then put x into z 
        if z contains "Revolution" then add 1 to tRevHits
        put  ("1.1"&quote&" 200 ") into tCompleteCode
        put  ("1.1"&quote&" 206 ") into tPartialCode
        if z contains tCompleteCode then add 1 to tCompleted
        if z contains tPartialCode then add 1 to tPartials
        put empty into z
        put x & cr after tFoundLInes
     end if

and now I get consistent, on each run:
Summary: Downloaded with Revo HT Navigator: 205 
Complete Downloads via HT site: 840
Partial Downloads 206's (mostly failures, some successes): 2877
numbers verified in BBEDit with Search and Replace on those strings... 
But still leave Questions 1 and 2 unanswer: why are local vars carrying values 
across sessions and how is a string that doesn't exist in the text being found 
at all?

I'm not sure I'll be able to answer either of those questions, but it's a 
lesson in good practice on initializing varibles, even locals.

Thanks for the help... Now we can dig the  logs.
