quicksheet example do not work properly ?

Hello,

I try to take the example from the quicksheets to solve PDE with Pdesolve. But even this example doesn't work properly:

Into the Pdesolve block, the limits for the x variable (2nd component of the vector, L) appears in red, with the error description "This variable reference is ambiguous". I try to correct it by adding a namespace operator, as described into the help, but in this case the error is always here. Even by putting a numeric avalue instead of L, the error persists.

I use Mathcad 14.

Can someone help to suppress this error ?

Thanks for answer.

Pierre,

Did you fully uninstall Mathcad 14, then reinstall? I don't know why else you would see an error, that no-one else is seeing.

I tried replacing the L with 6.28 as you did, and then I see an error message, that "the boundary conditions are not consistent with the endpoints specified for the spatial range." Try substituting the value of 2pi for L, which is its value in the worksheet.
