Just to let you know the " +x " will allow all access to the designated directory or file. I',m not sure what your trying to do, but here are some combinations to allow permissions somewhat more safe.
chmod u=rx file (Give the owner rx permissions, not w)
chmod go-rwx file (Deny rwx permission for group, others)
chmod g+w file (Give write permission to the group)
chmod a+x file1 file2 (Give execute permission to everybody)
chmod g+rx,o+x file (OK to combine like this with a comma)
