I am brand new to Maple.  I am using Maple 13.  When I try to create a direction field for the ODE dy/dt=.2ty I get the intended result.  When I try to create the same direction field using the ODE dy/dx=.2xy I recieve the following warning.

"Warning, y is present as both a dependent variable and a name.  Inconsisent specification of the dependent variable is deprecated, and it is assumed that the name is being used in place of the dependent variable".

Can someone explain why I get that error.  Am I doing something wrong?

Thanks,
