I can't get Bloomberg Screening (EQS) to work, any suggestions?

I am having problems with getting the Bloomberg screening functionality (EQS) to work in my R2012 version. I have installed datafeed toolbox and am having no problems pulling other data but I seem to be stuck on this.

I have a screen in Bloomberg called 'GiantCap' and I have tried to pull it into the system as follows:

javaaddpath({'C:\blp\API\blpapi3.jar'})

c=blp;

d = eqs(c,'GiantCap')

When I use this coding, I get the following message:

Undefined function 'eqs' for input arguments of type 'blp'.

The 'GiantCap' screen has no problems being pulled into excel. I believe I have followed all directions on Mathwork's Documentation Center. Any ideas would be greatly appreciated. Thanks!
