No members available for a vector of structs

I have a template class called Heap. My problem is that I want to implement the insert function at the bottom. But I can't reach the member variable of the Values vector. When I write Values[hole/2].tall it can't reach it(tall variable does not come directly after writing the dot). So can anybody please explain this ?

template <class Comparable>
class Heap
{
...
private:
// I have this vector
vector <heightNode <Comparable>> Values

};

template <typename Comparable>
struct heightNode
{
    Comparable tall;
    Comparable label;

    heightNode(const Comparable & t = Comparable(), const Comparable & la = Comparable()): tall(t),label(la) {}

    heightNode(const heightNode & rhs): tall(rhs.tall),label(rhs.label){}
};


template <class Comparable>
void Heap <Comparable>:: insert (const Comparable & value, const int & label)
{
    if(isFull())
    {
        cout <<"Heap is Full";
    }
    else
    {
        ++currentSize;//hole is an index we will put it to the last point in the vector.
        for(int hole=currentSize; hole>1 && (value > Values[hole/2].tall)); hole/=2 )
        {

        }
    }
}

This 

for(int hole=currentSize; hole>1 && (value > Values[hole/2].tall)); hole/=2 )

contains a surplus round closing bracket; make it 

for (int hole=currentSize; hole>1 && (value > Values[hole/2].tall); hole/=2)
