Doubts with the MCNP software for my thesis

Hello, it's a privilege to enter in this forum. My name is Geovanny, i'm from Mexico and i'm a student from the Autonomous Yucatan University. I'm studying in my last semester of Physical Engineering and i have some doubts about de MCNP software.

One of those is the next message that VISEDX give me when i try to open my code: "fatal error. facet 1.0 of tally 1 does not exist." I don´t know what exactly means these message. I hope this question isn´t silly.

Thank´s and nice to meet you.

Hi,
Difficult to help you with no input file.
I suppose that you try to calculate a f1 tally on a surface but this surface is not describe in your input file.

Sorry, you're right, i'll give you my input file to review it. I was thinking that the problem is in my cell card but i've been checking the file and don't find some error becuase VISED plot my geometry. Thanks a lot.

Geomtry 15 is strange
15 1 rcc ? I think it is the problem
It is better if you put your file in ascii in this forum
 
The geometry 15 is a rigth circular cilinder at the middle of the canon rotated 135 degrees. I found in the MCNP manual (page 4-15) that´s the way to rotate the geometry, maybe i use it in a wrong way. Here's my code:
