Problem with MS Visual C++ 7.0 getline function

I get this error each time I use the getline function. I am using MS
Visual C++ 7.0.

error C2780 :
'std::basic_istream<_elem,_Traits>&std::getline(std::basic_istream<_Elem,_T=
raits>&,std::basic_string>_Elem,_Traits,_Alloc>&,const
_Elem)':3 arguments attendus - 2 fournis

Here is a part of my code. Can you tell me why I am getting these
errors? Thanks for the help!!
