I realize my code is too long and not clear. This is the code after trimming
and commenting: (I use finaltotal array because string or number cannot be
passed by reference to cffunction)
<cfdump var="#session.finaltotal#">
<cffunction name="increasetotal" output="no" hint="update total">
<cfargument name="finaltotal" type="array">
<cfset temp1 = session.finaltotal[1] + 20>
<cfset ArraySet( ARGUMENTS.finaltotal,1,1, temp1 ) />
<cfreturn ARGUMENTS.finaltotal[1]>
</cffunction>
<cffunction name="decreasetotal" output="no" hint="update total">
<cfargument name="finaltotal" type="array">
<cfset temp2 = ARGUMENTS.finaltotal[1] - 10>
<cfset ArraySet( ARGUMENTS.finaltotal,1,1, temp2 ) />
<cfreturn ARGUMENTS.finaltotal[1]>
</cffunction>
<!--Javascript function to be called onClick -->
<script>
<cfoutput>
function hello(checkboxes, index)
{
checkbox = checkboxes[index];
if(!checkbox) {
checkbox = checkboxes;
}
var temp = 0;
if(checkbox.checked) {
temp = #increasetotal(session.finaltotal)#;
} else if (!checkbox.checked){
temp = #decreasetotal(session.finaltotal)#;
}
window.location.reload();
}
</cfoutput>
</script>
<!--HTML containing checkbox -->
<html><head><title></title></head>
<body>
<cfoutput>
<cfform NAME="listForm" METHOD="POST"
ACTION="http://www.annistonmorningrotary.org/temp/confirmpremium.cfm";>
<table border=1>
<tr><td><cfinput type="checkbox" name="chosenSite" value="1"
onclick="javascript:hello(document.listForm.chosenSite, 0);"/>
</table>
</cfform>
</cfoutput>
</body>
