Batch script not getting values from file

Specs: Windows XP, N/A
Hello,

I'm writing a batch script to copy some files, run a program (SARA) and read values from a file which SARA generates (chunklog.inf) - (and a bunch of other stuff not important here.)

However I'm having a major issue getting the values from chunklog.inf files to variables.

For example under where it says:
"rem fetch the current timecode from chunklog.inf" - I want to extract some text from chunklog.inf and place it in a file called timecode.txt - I then want to read the contents of timecode.txt into a variable and from that, pick the first 7 letters.

Only problem is that I cannot get this part to work. timecode.txt holds the correct values but %_TIMECODE% and %TIMECODE% never gets assigned any values.

Something which is strange is that if I take out this bit of code and place it in its batch script and run that seperately (in a folder where chunklog.inf also exists) then it works perfectly...

Any of you have a clue of what's wrong?

The script:

if [%1]==[-v] set VERBOSE=YES

rem --//
call :writelog "run bart.exe"
echo "bart.exe -restore -connect 5993 -gemdbdir %PROCESSDIR% -chunkdepot %DEPOTDIR% -login %LOGINname% -password %LOGINPASS%"

)

:END

An example of chunklog.inf:
#dump of chunklog information generated by SARA
((int) 0) = (((string) "/LogPlatformInstances/Demonstration LogPlatforms/W86047"(string) "W86047:2009 12 26 22:12:39"(string) "Demo chunklog created by Sara"(string) "RA6AXK0"(time) 1260887993.000000(time) 1261887159.000000(string) "chunks"))

i think you need exclms here:
SET TIMECODE=!_TIMECODE:~0,7!

if [!TIMECODE!]==[] (
call :writelog "A timecode could not be read from chunklog.inf"
GOTO :ERROR
)

call :writelog "Opened chunklog.inf and found the current timecode to be !TIMECODE!"

and all similar references,. change %TIMECODE% to !TIMECODE!
see if that helps.
