Hi @thuanhuynhh, where did you get the .csl file from, or how have you created/changed it etc.?
Thanks a lot!

Hi @bozana , I have get csl file from my zotero software
Or you can check this file from here https://github.com/citation-style-language/styles/blob/master/national-library-of-medicine-grant-proposals.csl or https://www.zotero.org/styles?q=nlm

Hi @thuanhuynhh, sorry for such a delay :-(
Why have you changed that file? -- I understand you have changed the title, but why id and links?
(I do not have a good understanding what id and links mean and what implication changing them that could have...)
