What is the one causing Problems?

EDIT:

public CheckAccount(playerid, account[])
{
    new rows, field;
    cache_get_data(rows, field);
    if(rows>=1)
    {
        ShowPlayerDialog(playerid, LOGIN, DIALOG_STYLE_PASSWORD, "Welcome back","Welcome back to Contract Wars!\n\nType in your password below to login","Login","Leave");
        accountExists[playerid] = true;
    }
    else
    {
        ShowPlayerDialog(playerid, REGISTER, DIALOG_STYLE_PASSWORD, "New account","Please input your password below to register a account","Register","Leave");
        accountExists[playerid] = false;
    }
    return 1;
}
public CheckAccountEx(account[])
{
    new rows, field;
    cache_get_data(rows, field);
    if(rows >= 1) { QueryState = true; }
    else { QueryState = false; }
    return QueryState;
}

cache_get_data comes in these two lines.
line 359-382

Edit: If i use cache_get_row_count(), it says error 017: undefined symbol "cache_get_row_count"
