Bash variable available for use outside loop

In the below for loop, I extract a variable $d which is an id that will change each time. The bash executes the problem that I am having is that p (after the done) is the path with the extracted $d. However, I can not use it in subsequent loops as it is not reconized. I have been trying to change the code so that I can use p in other loops but can not seem to. I added comments as well. Thank you Smilie.

Code:
for f in /path/to/file/*.zip ; do
    echo "Start directory creation: $(date) - file: $f" >> "$d"/processing.log # log start
     bname=`basename $f` # strip of path
     d="$(echo $bname|cut -d_ -f1)" # remove after first underscore
     unzip $f -d /path/to/file/$d  # unzip folder
#rm -rf $file
      cp /path/to/file/$d/Variants/${d}_v1_${d}_RNA_v1/*full.tsv /path/to/file/ # copy full.tsv for analysis
      cp /path/to/file/$d/Variants/${d}_v1_${d}_RNA_v1/*Non-Filtered*.vcf /path/to/file/  # copy Non-Filtered.vcf for analysis
      mv /path/to/file/$d /path/to/file/
    echo "End directory creation: $(date) - file: $f" >> "$d"/processing.log # log end
done  # end loop
p=/path/to/file/$d  # store path in p
echo $p   # test output
