I can't get this code to work on my server.
<tmpl_var gift_date> produces variable like 01/01/2009 I need it to be converted to the class gift2009
The code does work on my local machine if i convert <tmpl_var gift_date> to 01/01/2009. Also if i were to just hard code a class it does work on the server but that would give all the years the same class and I only need the 1 year to be added and totaled seperately

This is all I want:
<div class="gift2009">
<div class="gift2009">
From where would the "gift2009" come?
If it's something that can be "hard coded", why no just write it?
If it's something that can be "hard coded", why no just write it?
document.write( '<div id="gift2009" class="gift2009" >' )
Or, better yet, something like this...
I'm confused. :-)

You could even add a parameter to addAll()...
Then the "body" tag would look like:
<body onload='addAdd("gift2009")

<body onload='addAdd("gift2009")
function addAll( className ){
var gifts = getElementsByClass( className )

If I hard code the class then all the years will have the same class so instead of just telling me how much someone gave in 2009 it would add up the persons complete giving history.
So I am using your javascript to pick and choose which years to add up, but to do this I have to make sure that all the years have different classes.

the only way for me to make sure that the donations gave in 2009 are equipped with class="gift2009" and year 2008 equipped with class="gift2008" is to use the <tmpl_var gift_date> variable and get it converted to the class of the year

Am I making sense?
But <tmpl_var gift_date> is not a variable. It is a string.
From where is this value supposed to be obtained?

This is using the HTML::Template Perl module attatched to my CMS. So when I write the string <tmpl_var gift_date> it gives me the date from the database which i dont have access to. Likewise for the value of each gift all I have to put is<tmpl_var gift_amount>.

Here is what I absolutely now know:
I know that my replace character script is creating the desired class.
The combination of the addition script and the replace character script do work together.
Both scripts work with the <tmpl_var gift_date> string
When both scripts and the string are all put together the replace character script works but the addition script does not.
Is there anyway of troubleshooting this or is this a hopeless cause. I have to get this to work but I don't know what other rout to take.

I have no clue what I did but it works! It wasn't working and I was making sure the code was clean before i posted it in here, and then bam, it worked! Thank you for your patience, and for the code this morning.
God Bless you

generates an invalid <div...> tag.
Take a look at what is in the alert dialog box...
What would you expect/hope the div to look like?
