Switches on webserver

All 5 gauges work just fine but I am unable to get these switches to respond. I don't even want the switch to work far as turning on or off any relays I just want a status of on or off and since this HTML was already built I figured to use the switches as status.

Did You post Arduino forum by mistake? It looks like a message to a friend working in the project.

Please read this link: How to get the best out of this forum - Using Arduino / Project Guidance - Arduino Forum

your XML_response() function is responsible for sending the data back to the client. It currently does NOT send any data that is tagged as 'SW' like your client side code is expecting

What is an example of a code to call for SW to flip for the pumpPin == LOW?

I have tried to call it by strSW, SW, SW1, then if checked, else unchecked codes and no results

Yeah. No friends here. : )
Why copy/paste 400 lines of code that you have no idea how to rend dor your purpose and need help from around the world, when you can create your own from scratch, with nothing more than notepad, and have complete control on how it works? HTML is easy to learn, and very forgiving.

I got it
