I need some help with a C# if/then statement

[dyetube]

For some reason I keep getting this error: Operator '&&' cannot be applied to operands of type 'bool' and 'int' When I try to run this if then statement:

if (majorOutages <= 3 && dTimePercentage = 6) flmajorOutages = 6;
if (majorOutages <= 3 && dTimePercentage = 5) flmajorOutages = 5;
if (majorOutages <= 3 && dTimePercentage = 4) flmajorOutages = 4;
if (majorOutages <= 3 && dTimePercentage = 3) flmajorOutages = 3;
if (majorOutages <= 3 && dTimePercentage = 2) flmajorOutages = 2;

Any ideas why? If you need any more of my code, let me know! Thanks!

Equels comparison is done with ==

if (majorOutages <= 3 && dTimePercentage == 6) flmajorOutages = 6;
if (majorOutages <= 3 && dTimePercentage == 5) flmajorOutages = 5;
if (majorOutages <= 3 && dTimePercentage == 4) flmajorOutages = 4;
if (majorOutages <= 3 && dTimePercentage == 3) flmajorOutages = 3;
if (majorOutages <= 3 && dTimePercentage == 2) flmajorOutages = 2;

Also, do yourself a favor next time and use a switch

Thanks! I am a newbie to c#. I actually am using a switch. Maybe I am going about this the wrong way?? here is the full code:

//check how many outages and calculate with downtime percentage
        switch (Convert.ToInt32(flmajorOutages))
        {
            case 1:
                dTimePercentage = 1;                
                break;
            case 2:
                dTimePercentage = 1;               
                break;
            case 3:
                dTimePercentage = 2;
                break;
            case 4:
                dTimePercentage = 3;                
                break;
            case 5:
                dTimePercentage = 4;               
                break;
            case 6:
                dTimePercentage = 5;                
                break;
            case 7:
                dTimePercentage = 6;
                break;
            default:
                dTimePercentage = 6;
                break;
        }

        if (majorOutages >= 8) flmajorOutages = 6;
        if (majorOutages <= 7) flmajorOutages = 5;
        if (majorOutages <= 5) flmajorOutages = 4;
        if (majorOutages <= 3 && dTimePercentage = 6) flmajorOutages = 6;
        if (majorOutages <= 3 && dTimePercentage = 5) flmajorOutages = 5;
        if (majorOutages <= 3 && dTimePercentage = 4) flmajorOutages = 4;
        if (majorOutages <= 3 && dTimePercentage = 3) flmajorOutages = 3;
        if (majorOutages <= 3 && dTimePercentage = 2) flmajorOutages = 2;
      
        string BusEffFactorGraph;
        string networkScore;
        switch (flmajorOutages)
        {
            case 1:
                BusEffFactorGraph = "66";
                networkScore = "Above Average";
                break;
            case 2:
                BusEffFactorGraph = "66";
                networkScore = "Above Average";
                break;
            case 3:
                BusEffFactorGraph = "99";
                networkScore = "Average";
                break;
            case 4:
                BusEffFactorGraph = "133";
                networkScore = "Below Average";
                break;
            case 5:
                BusEffFactorGraph = "166";
                networkScore = "Poor";
                break;
            case 6:
                BusEffFactorGraph = "200";
                networkScore = "Failing";
                break;
            case 7:
                BusEffFactorGraph = "220";
                networkScore = "Failing";
                break;
            case 8:
                BusEffFactorGraph = "250";
                networkScore = "Failing";
                break;
            default:
                BusEffFactorGraph = "250";
                networkScore = "Failing";
                break;
        }

I am just tweaking that was already written before I was here so the second switch was already in place and I had to add the first switch... Any help is greatly appreciated! Thank you!
