The package modt

SIRsh=Module[{S,Vg,var}, var= {s, i, v};
    S={{\[Mu] N,-\[Beta]/Nv,0,      -\[Mu],0,0},
       {0,  \[Beta]/Nv,0,       0,-\[Mu]i,0},
       {0,  0,  -\[Beta]v/N,   0,\[Beta]v Nv/N,-\[Nu]}};
    Vg={1,g[s,v],h[i,v], s  ,i , v }; 
$ContextPath = DeleteDuplicates[Append
[$ContextPath, "modt`Private`"

includes a script which introduces in var= {s, i, v} three local variables s,i,v. For some reason, v is interpreted differently from s,i and later when I call it


I get warning messages like Globalv::shdw: Symbol v appears in multiple contexts {Global,modsPrivate}; or g[s, modtPrivatev] which warn me about v, but not about s,i. What could be the difference?

    $\begingroup$ Works for me. Start a new kernel and try again. $\endgroup$ Feb 7 at 13:12
  • $\begingroup$ I restarted (5 times) but still I got {1, g[s, modtPrivatev], h[i, modtPrivatev], s, i, modtPrivatev}, and v is in red. To be sure, I quit Mathematica. Still, v is seen differently than s,i on my 13.3 $\endgroup$

    $\begingroup$ I have 14.0. Maybe that is the reason. $\endgroup$ Feb 7 at 16:15
  • $\begingroup$ At least it works almost fine if I take the script out of the package and add it where I use it. v is still in red (with no error message!), but the results are fine $\endgroup$
