Illegal pair_coeff command

Thanks for the comment.

I fixed it and ran again.

I got a another error message.

"Invalid bond type in Bonds section of data file"

I think It may be a simple error just like before, though I don’t know what it is now.

Here’s my question.

If I have a grammatical mistake in input file, this can be easily solved by checking the log file.

But how do I know if the grammatical problem is in data file?
