[求助]不知道错在哪儿，各位指点一下。谢了

#include <iostream>
using namespace std;

short int Divider(unsigned short int valone,unsigned short int valtwo);

int main()
{
unsigned short int one,two;
short int answer;
std::cout << "Enter two numbers.\n Number one:" ;
std::cin >> one;
std::cout << "Number two:" << "\n";
std::cin >> two;
answer = Divider(one,two);

if (answer > -1);
std::cout << "Answer:" << answer;
else
std::cout << "Error,can't divider by zero!";

char response;
std::cin >> response;
return 0;
}

short int Divider(unsigned short int valone,unsigned short int valtwo)
{
if (valTwo == 0)
return -1;
else
return valOne/valTwo;
}

编译提示： syntax error before `else'

我理解的意思是说在“else”之前有语法错误，不知道是我理解错了，还是我编写的时候哪儿出错了。

请各位赐教。
