The build PDF fails on the EM of Elsevier.

For revision, they ask "editable files" so it is not possible to upload the PDF directly compiled from my LaTeX manuscript.

Several questions:

- Is the order of the file important ?

- The figures (in .pdf or in .png) have to be added as "Figure" or as "Manuscript files" for the LaTeX rendering ?

- What about the .cls, .bib and .sty files ?

I really need help as the Elsevier Support Team do not answer me...

Thank you very much,
