@Juan Andres In general do not post images like above ones, they are not helping much. Just copy/paste the two lines of text with the ngspice error and attach the complete

.spice

file you are trying to simulate, so we can investigate the problem.

Ok, I'm sorry

No problem. Ngspice errors are often not very clear, and difficult to understand and fix. This happens to everyone who does simulations, so welcome to the club!
