Bash cd into subdirectories with increment name

I have a list of folders in current directory with name "S01.result" up to "S15.result", amongst other stuff. I'm trying to write a script that cd into each folder with name pattern "sXX.result" and do something within each subdirectory.

This is what I'm trying:

ext = ".result"
echo -n "Enter the number of your first subject."
read start
echo -n "Enter the number of your last subject. "
read end

for i in {start..end};
do
  if [[i < 10]]; then
    name = "s0$i&ext"
    echo $name
  else 
    name = "s$i$ext"
    echo $name
  fi

  #src is the path of current directory
  if [ -d "$src/$name" ]; then 
    cd "$src/$name"
    #do some other things here 
  fi
done

Am I concatenating the filename correctly and am I finding the subdirectory correctly? Is there any better way to do it?

You said you need to cd into each folder that matches the pattern, so we can iterate through all files/folders in current directory for those subdirectories that match the desired pattern.

#!/bin/bash

# Get current working directory
src=$(pwd)

# Pattern match as you described
regex="^s[0-9]{2}\.result$"

# Everything in current directory
for dir in "$src"/*; do

    # If this is a directory that matches the pattern, cd to it
    # Will early terminate on non-directories
    if test -d $dir && [[ $dir =~ $regex ]]; then
        cd "$dir"
        # Do some other things here 
    fi
done
