List all the subdirectories of a chosen folder / bash script

I have an issye with my script. I have to write a script which collects information about each subfolder in the folder given as an argument, including: the name of the subfolder and the number of files in it (ls ... |wc -l). That's what I tried... But it doesn't search in one folder but in all of these.

#!/bin/bash
read $name

for i in $name/*;
do
        [ -d "$i" ] && echo ${i##*/} $(ls -l "$i" | wc -l);
done

In general you don't want to parse the output of ls in a script. Perhaps try something like this:

#!/bin/bash
read name
shopt -s nullglob
for i in "${name}"/* ; do
  if [[ -d "${i}" ]] ; then
    i_files=( "${i}"/* )
    echo "${i##*/}" "${#i_files[@]}"
  fi
done

This puts the list of files in each directory into an array, then prints the length of the array. shopt -s nullglob is necessary to ensure that the array is empty if there are no files inside the directory, otherwise the array will be length 1 and contain the unmatched glob in its unexpanded form.
