problem with range variable

It displays fine for me. Which version of Mathcad and which OS are you using?

Does the problem go away if you either a) Close the worksheet and then reopen it?  b).  type "x =" somewhere else on the worksheet?

There is an intermittent problem that some people have reported whereby an evaluation doesn't display anything, but it cured by one of the above two actions. (I've certainly experienced it).

Im using mathcad 15 and w8

I had another internal error with graphs "traces".,then i found it how to solve it  in here:

Re: Mathcad 14: Graph "Traces" causing "internal error..."

1. Go to uninstall programs

2. Find Mathcad and repair it

3. A box will ask for Mathcad15WixInstaller.msi browse for it (Mathcad15_EN folder -> mathcad -> Mathcad15WixInstaller.msi)

4. and BAM! problem solved.

by solving that error this one was also solved.
