Pointer to pointer to struct in C

I'm making stack implementation in C using pointers and struct. Push and crateStack functions work well (both of them create new element in memory). Anyway, pop function doesnt work and I dont know why, here is code of that function:

int pop(element **lastStackEl)
{
  int poppedValue = *lastStackEl->value;
  element *temp = *lastStackEl->prev;
  free(*lastStackEl);
  *lastStackEl=temp;
  return poppedValue;
}

And here is my struct:

typedef struct Element {
  int value;
  struct Element *prev;
} element;

The compiler's giving error in first and second line of pop function:

error: request for member 'value' in something not a structure or union
int poppedValue = *lastStackEl->value;
