How do I get a count of files in a windows directory and store it in a variable for comparison with another directory

I have a script that I execute every evening and one of the things that I do is an xcopy of the backup files from a source directory to a target directory on a backup server. What I would like to do is after the xcopy is count the number of files in the source directory and store that amount in a variable and I would like to do the same for the target directory. Then compare the amounts if the target directory number of files aren't the same then send a message stating that the copy wasn't sucessful then goto end. If they are the same then logic should fall through to next if statement. So far this is what I've got so far some of you guys may have seen this before.
Thanks,
