Solve block solves it, but variable is undefined

Hi,

look like solving block solves the equation, but lower, it says that the variable is undefined. What am I missing?

Hi,

In one of the equations in the solve block it ends on the right-hand end of equation with multiply apostrophe as a mistake and hangs the solve block.

Correct the equation by deleting the multiply apostrophe and the solve block works.  It takes a while on my very fast machine so be patient.

Cheers
