[Equest-users] DOE 2 Expressions

[Saif A via Equest-users]

Thank you very much guys,

I have found  the resources you recommended on the web. I went through them
quickly and they look very helpful. Also your instructions about the
keywords are great, now I know where to start.

Really appreciate it.

Saif,
