The problem is the subscript - your definition has full form:
\!\(test[_\ Subscript[v, 0], \[Gamma]_, H_,
m_] := \(-\(\(\((m\ H)\)\ Cosh[
ArcSinh[\(Subscript[v, 0]\ \
\[Gamma]\)\/H]]\)\/\[Gamma]\^2\)\) - \(m\ ArcSinh[\(Subscript[v, 0]\ \
\[Gamma]\)\/H]\ Subscript[v, 0]\)\/\[Gamma]\)
try
\!\(test[v0_, \ \[Gamma]_, \ H_, \
m_] := \((\(\(-m\)*H\)\/\[Gamma]\^2*Cosh[ArcSinh[v0*\[Gamma]\/H]] -
m\/\[Gamma]*ArcSinh[v0*\[Gamma]\/H]*v0)\)\)
instead.
