If condition not working for ethenet shield?

Using Arduino Programming Questions
#1

Hello, I’m making website to see temperature levels, using LM35 IC and, arduino Ethernet shield.

tempC1 = analogRead(temp_input_pin_01); // taking value from senser ( temp_input_pin_01 ) and save it in to tempC1.
    tempC1 = (5.0*tempC1*100.0)/1024.0 ;

if (tempC1 >= 45)
     {
       digitalWrite(cooling_fan_01,HIGH);
     }
   else
     {
       digitalWrite(cooling_fan_01,LOW);
     } 


//and this is in html section

 client.println("<div class='col-md-2'>");
          client.println("<div class='panel panel-warning'>");
          client.println("<div class='panel-heading'>");
          client.println("<h3 class='panel-title' align='center'>Temperature 01</h3>");
          client.println("</div>");
          client.println("<div class='panel-body'>");
         if(tempC1 >= 45)
          {
          client.println("<img src='http://miracle.lk/MPB_NCE/13.jpg'width='112' height='110'align='center'>");
          }
          else 
          {
          client.println("<img src='http://miracle.lk/MPB_NCE/14.jpg'width='112' height='110'align='center'>"); 
          }
          client.println("<div class='container' align='center'></div>");
          client.println("</div>");
          client.println("</div>");
          client.println("</div>");

this is not working, at least http request also not working, but if I use any other condition, (or other variable) this is working perfectly. I can’t understand why this is happening.

please some one help me…
thank you

Try here

this is not working

The code does something. Only you can see what it does.
You want the code to do something. Only you know what that it.

All we can tell from this statement is that what you want is not what you get.

#4

yes, exactly. here problem is that if I use "IF"condition, html request will not work.

Maybe you're running out of RAM, but from the snippet posted, who can tell?
