How do I add the option to change the path in a menu?

How do I add the option to change the path in a menu? I have this script. The user chooses a number and had the option of doing something, looking for log files etc. There is a possibility they might want to look at a different path other than what I have given them such as /home/demo/logs/current So if I wanted to give them the option to change the path, how could I do this? Thanks.

7)echo "enter your time criteria here"
read var_2;
cd /home/demo/current_release/logs/current
grep -i "$var_1" *.log|grep -i "$var_2"|sort -u |more

Anyone?

No help, very disappointed. OK, I'll stop asking and figure it out myself.
