Iterators, need help.

I keep getting this error and I dont know why.
Line 107: Just before my main.
[Error] cast from 'NodeType*' to 'unsigned int' loses precision [-fpermissive]

I also need to add statements to ListType that will display the address of the start pointer, the address pointed by next, the data contents of the node pointed to by next and the link pointer value in node pointed to by next. I do not know how to do this.

I know the statements should look something like (unsigned int)start, but that leads me back to the same error I am already getting in earlier code.

#include <cstdlib>
#include <iostream>
using namespace std;

void deleteVal(NodeType *);
void addValToEnd(string);


};

NodeType *ListType::searchList(string who)

while(name != "xxx")
{

My apologies, I will repost. I am just in a rush.
