PHP HTML Image Map Form

[htmlguy2000]

I did a little looking around and I cannot get this form to work. It has been a few years since I have done any HTML work so if I overlooked something any assistance would be great.

I was only working on getting the Temp_Up button to work and once that was operating I was going to edit the rest of the code.

<img id="ACRemote" src="ac_remote.png" border="0"

width="191" height="349" orgWidth="191" orgHeight="349" usemap="#ACRemote" alt="" />
<form name"ACForm" action="" method="post">

<map name="ACRemote" id="ACRemote">

<area alt="" title="AC_On" shape="rect" coords="17,12,82,67" style="outline:none;" target="_self" onclick="onclick" />
<area alt="Fan_Up" title="Fan_Up" shape="rect" coords="11,84,68,140" style="outline:none;" target="_self" onclick="On_Click" />
<area alt="Fan_Down" title="Fan_Down" shape="rect" coords="12,158,67,210" style="outline:none;" target="_self" onclick="On_Click" />
<area alt="Cool" title="Cool" shape="rect" coords="67,125,124,179" style="outline:none;" target="_self" onclick="On_Click" />
<area alt="Temp_Up" title="Temp_Up" shape="rect" coords="124,83,181,137" style="outline:none;" onclick="document.ACForm.submit()" name ="Cool" value="Cool"/>
<area alt="Temp_Down" title="Temp_Down" shape="rect" coords="124,161,181,215" style="outline:none;" target="_self" onclick="On_Click" />
<area alt="Energy_Svr" title="Energy_Svr" shape="rect" coords="67,201,124,255" style="outline:none;" target="_self" onclick="On_Click" />
<area alt="Auto_Fan" title="Auto_Fan" shape="rect" coords="6,234,63,288" style="outline:none;" target="_self" onclick="On_Click" />
<area alt="Fan_Only" title="Fan_Only" shape="rect" coords="69,282,126,336" style="outline:none;" target="_self" onclick="On_Click" />
</map>
</form>




<?php
if(isset($_GET['Cooler'])) {
CoolerFunc();
}
if(isset($_GET['Cool'])) {
CoolFunc();
}
if(isset($_GET['Warm'])) {
WarmFunc();
}
if(isset($_GET['Warmer'])) {
WarmerFunc();
}

function CoolerFunc(){
echo "Cooler Button Clicked";
$output = shell_exec('/home/pi/./acd5');

}
function CoolFunc(){
echo "Cool Button Clicked";
$output = shell_exec('irsend SEND_ONCE ac KEY_KPMINUS');

}
function WarmFunc(){
echo "Warm Button Clicked";
$output = shell_exec('irsend SEND_ONCE ac KEY_KPPLUS');

}
function WarmerFunc(){
echo "Warmer Button clicked";
$output = shell_exec('/home/pi/./acu5');

}
?>

Thanks again.
