Please use better titles for your posting. "Error?" could mean just about anything, and does not help readers find information that is relevant to _their_ work.

Zone 1 gg ??? Operands to the and && operators must be convertible to logical scalar values.

The reasons for this are likely to be similar to your other question:
http://www.mathworks.co.uk/matlabcentral/answers/11809-help-in-solver-error
which is probably the divide by zero error. Fix this first and then see if have another error.

@Rick: I like your matter-of-fact style to answer questions, which cannot be answered. This is valuable for the forum. +1

@Jan: I am trying very hard to stay focused on facts and data, but it is becoming very challenging. Thanks for the kudos!
