Get value from string

Hi i was trying to write a script to give input and create a file using the value from the input
EXAMPLE: if my input in 20130508 i want to get the value 13 and and create a dir and same aplies to 05 and 08

i tried something like but didnt get what i expected
Code:
#!/bin/bash
#Cleaning up the source file
INPUTDATE=$1
A=$INPUTDATE  | cut -d/ -f4
mkdir $A

any help will be greatefull
# 2  
Use substring extraction:
Code:
mkdir ${INPUTDATE:2:2} ${INPUTDATE:4:2} ${INPUTDATE:6:2}

Syntax:
Code:
${string:position:length}

This User Gave Thanks to Yoda For This Post:
# 3  
Your wanted
Code:
A=$(echo "$INPUTDATE"  | cut -d/ -f4)
mkdir "$A"

Perhaps you can simplify with
Code:
A=${INPUTDATE##*/}

or
Code:
A=${INPUTDATE//*\//}
