I am having problems sorting items within a spreadsheet that contain a forward slash "/". Below is an example of the data I'm trying to sort along with the error I'm receiving...

Data set:

1A/2/1
1A/2/2
1A/2/3
1A/2/10
1A/2/11
1A/2/12
1A/2/20
1A/2/21
1A/2/22
1A/2/30
1A/2/31
1A/2/32

The problem is that when I sort ascending, my data now appears like this:

1A/2/1
1A/2/10
1A/2/11
1A/2/12
1A/2/2
1A/2/20
1A/2/21
1A/2/22
1A/2/3
1A/2/30
1A/2/31
1A/2/32

How do I remedy this problem? Can I remedy this problem?
