This sounds a bit like a truncation issue.
If you do something like
command1 > bar
# some code
command2 > bar
then the second redirect will truncate the file to 0 bytes
before redirecting the output from command2 into it.
Try using >> instead of >, as it appends to the file.
If this doesn't help, please post the script (or a simplified
version thereof). We're not clairvoyant, you know... :)
HTH,
