Why I got PSPICE error message as"Less than 2 connections at node 1"

Why did I get a PSpice error message as"Less than 2 connections at node 1"

Below is my description for a simple and easy circuit(just series of two resistor and one source),and I use PSpice Stduent.

Vin 1 0 DC
Ra 1 2 1k
Rb 2 0 1k
.PROBE

but it make error in PSPICE as below


**** 07/29/12 21:21:12 *********** Evaluation PSpice (Nov 1999) **************

Vin 1 0 DC 1V


**** CIRCUIT DESCRIPTION

Ra 1 2 1k
Rb 2 0 1k
.PROBE

ERROR -- Less than 2 connections at node 1

I am puzzled what the error "Less than 2 connections at node 1" means,I have connected all node ,none is leave.

I am puzzled by what you actually used. The earlier part of your post shows

Vin 1 0 DC

Which is missing a voltage e.g.

Vin 1 0 DC 5

But later in your post you show

Vin 1 0 DC 1V

What have you actually used?

I used Vin 1 0 DC 1V ,thanks.

The description is :

Vin 1 0 DC 1V
Ra 1 2 1k
Rb 2 0 1k
.PROBE


The simulating result is

I also write another text file for test,which is as below:

Vin 1 0 DC 1V
R1 1 0 1k
.PROBE

It also exhibits the same error message " Less than 2 connections at node 1"

The first line is being ignored as a title statement - the simulation should start on the second line. Add any text on the first line as a title.

It worked.Thanks.

Hello to every body, i am new here and i need your help. i have circuit designed in OrCAD capture cis lite. i am getting ERROR(ORPSIM-15141): Less than 2 connections at node N02458. how i can get ride of this problem.
