Need help with calling fucntions

Projects Programming

I am having issues on trying to call the functions on my project. This part of the code:
client.println("");
client.println("");
client.println("");
client.println("");
client.println("");
if(readString.indexOf("relayon") ==0)//checks for on
{
activate();
}
if(readString.indexOf("relayoff") >0)//checks for on
{
deactivate();
}
was supposed to call the following function whenever I have clicked the button but it is not doing so. Can you please look at my code and help me figure this out. Thanks

Good. While you're at it, could you include code tags?

Possibly what he meant?

if (something == 0)
{
  doThis();  // because it was '0'
}
else
{
  doOther();  // because it was NOT '0'
}

Use serial debug print lines on readstring and see where "relayon" and "relayoff" really are.

if(readString.indexOf("relayon") ==0)//checks for on
         {
           activate();
         }
         if(readString.indexOf("relayoff") >0)//checks for on
         {
           deactivate();
         }

The indexOf() function returns the position of the phrase in the String. It returns -1 if the phrase was not found. It is highly unlikely that the phrase relayon is at the start of the String obtained from the client.
