Lost connection to MySQL on MAMP after installing Zend Server CE

Question

I had MAMP running on my Mac. I installed Zend Server CE to debug the code in Zend's htdocs folder. PHP debugging works but the site cannot connect to MySQL on "localhost". Do I need to specify that it connects to Zend Server's MySQL? If so, how would I do that?

P.S. Zend Server is on //localhost:10081/, MAMP on //localhost:7777 , mamp's db has data in it, referred to as "localhost"..
