Problem "To extract COMSOL data "

Hi
I try to follow all the steps that is mentioned in the LIVELINK FOR MATLAB USER GUIDE

"Start to load the model busbar from the COMSOL model library, enter the command:

model = mphload('busbar');

To extract the temperature and the electric potential field, use the command mpheval
as below:

dat = mpheval(model, {'T' 'V'}, 'selection', 1);

To display the temperature field enter:

mphplot(dat, 'index', 1); "

but I obtain the following error .......

??? Error: File: mphplot.p Line: 2063 Column: 0 Expression or statement is incomplete or incorrect.

I do not understand why?

I appreciate any help !!
