C++ :: Calling Constructor Inside Another One (No Matching Function To Call)

I've written an Array class to create 1d,2d and 3d array and it works fine for every test : example of the constructor of the array class for 2d case:

Array::Array( int xSize, int ySize ) {
xSize_ = xSize;
ySize_ = ySize;
zSize_ = 1;
vec.resize(xSize*ySize);
}

It works fine , but when i need to use this constructor inside of other constructor, i get the "no matching function error" ,
part of my code:

class StaggeredGrid {
public:
StaggeredGrid ( int xSize1, int ySize1, real dx, real dy ) : p_ (2,2) {}
