Text shatters after pressing up arrow and changing bash prompt

So I recently decided to change my bash prompt and I have a problem. After pressing up arrow a few times so I don't have to write the command I used like a minute ago the command suddenly breaks the whole prompt and the characters are randomly shattered.

I added this to my bash profile:

export PS1="[\e[32m]\u[\e[m]@[\e[32m]\s[\e[m]-[\e[32m]\W[\e[m] >> "

After pressing the up arrow like two or three times, the characters become totally scrambled like this: 

do nano ~/.bash_profile-[]Downloads[] >> source ~/.bash_profile  
pwd                                                      sudo nano 
~/.bash_profile

Guys please help me, it's really annoying. Thanks.

    You need \[...\] around non-printing characters, not [...]. That's why you have a bunch of [] scattered throughout your prompt.
