[texworks] question

[Rodney]

Hello,
I have a question. I am using TeXworks pdflatex with a Macintosh and have a problem with 
the \input command. I have created a master file and a subfile. In the master file I
call the subfile with the input command:  \input{subfile}. However, nothing happens,
not even an error message. Could you please help me with this problem.
Thank you in advance.
Best regards,
Rodney Coleman
