Question: PDE Plotting Issue

Hello All,

 

I am having a problem plotting the solution of a system of PDE's.  Maple evauates to a module, but when I try to plot any of the dependent variables (of space and time) vs time, all I get back is:

 

"PLOT(...)"

 

My module is called Final, and so my plotting command is as follows:

p1:=Final:-plot(A(z,t),t=0.5);

 

This is where I get "PLOT(...)".  Any help would be greatly appreciated!!! Thanks!
