Why wont this compile?

#include <ctime>
using namespace std;
int main()
{
    //Array processing
    int info[5][2];     //Array with 10 elements
    int amt, amto, amtt, amtr, amtv;
    int x=0;          //counter
    int y;            //number of elements in array
    int value=0;      //input value
    int total=0;      //total
    float average;    //average
    int stop=0;
   
    cout<<"\nThis program will calculate the average of up to 10 numbers\n";
    while(value!=-1)
    {
            cout<<"Enter sales ID number: ";
            cin>>value;
            if (value=1)
            {
              cout<<"Enter sales amount: ";
              cin>>amto;
            )
            else if (value=2)
            {
              cout<<"Enter sales amount: ";
              cin>>amtt;
            )
            else if (value=3)
            {
              cout<<"Enter sales amount: ";
              cin>>amtr;
            )
            else if (value=4)
            {
              cout<<"Enter sales amount: ";
              cin>>amtf;
            )
            else if (value=5)
            {
              cout<<"Enter sales amount: ";
              cin>>amtv;
            }
            }

There's more stuff after it, but this is what's important.

I keep getting these errors.
"27 expected primary-expression before ')' token "
"27 expected `;' before ')' token "

Can anyone help me!?

Here's a classic C++ nub programmer, he can't solve his shitty program.

1) Learn C before C++(It makes C++ programmers less retarded)
2) Learn to read
3) Learn how to program
4) Learn the difference between {} and ()
5) Learn the difference between assignement and comparison operator
6) Become a hero
7) Do a barrel roll
8) Learn Java
9) ????
10) Profit

Here you go.
