`make` command not working for all targets specified

Question

I have to create a make file for building pdf and dvi files separately from 2 tex files.. resume.tex and article tex. What I have made looks like this:

 all: resume_all article_all 

 dvi: article_dvi resume_dvi

 pdf: resume_pdf article_pdf

 article_dvi : article.tex 
        latex article.tex
 article_pdf : article.tex ref.bib
        pdflatex article.tex
        bibtex article
        pdflatex article.tex
        pdflatex article.tex

 article_all : article.tex ref.bib
        latex article.tex
        bibtex article
        pdflatex article.tex
        pdflatex article.tex


 resume_dvi : resume.tex
        latex resume.tex

 resume_pdf : resume.tex
        pdflatex resume.tex

 resume_all : resume.tex
        pdflatex resume.tex
        latex resume.tex



 clean:
        rm -f *.log *.bak *.aux *.bbl *.blg *.idx *.toc *.out *~

 clean-all:
        rm -f *.dvi *.log *.bak *.aux *.bbl *.blg *.idx *.ps *.eps *.pdf *.toc *.out *~

What happens is when I run make on my terminal. Only the pdf for resume.tex is created. Nothing else happens. Same for all other definitions. Only the first target is executed.
