running simulink model from matlab

I am able to run the program in Matlab using >>sim ('PumpLocation');

but when I assign QQQ to a flow source (see pic1.JPG)

and use >>sim ('PumpLocation','QQQ','40') - it no longer works

I don't see a picture attached. If the following doesn't answer your question, please ensure to attach something and I can take a look.

Is QQQ just a workspace variable that feeds into a flow source? If so, you can do:

>> QQQ = 40;
>> simout1 = sim('PumpLocation','StopTime','20', ... );

>> QQQ = 50;
>> simout2 = sim('PumpLocatiom','StopTime','20', ... );
