# [texworks] Difficulty in updating

Wed Mar 24 17:30:50 CET 2021

Sir/Madam,
I have a latex file prepared using Texworks platform. The pdf is built without any problem by pressing the green arrow button on the top left corner. I added additional material/data at the end of the file (before \end{document} command). I pressed the green arrow again but there is no change in the output and additional material is ignored. How do I build and view the modified tex file ?
