To get HTMLArea to work, first upload everything you downloaded. I added this code right after the link to the stylesheet at the top of the document:
CODE
<script language="Javascript1.2"><!-- // load htmlarea
_editor_url = "http://www.yourdomain.com/htmlarea/"; // URL to htmlarea files
var win_ie_ver = parseFloat(navigator.appVersion.split("MSIE")[1]);
if (navigator.userAgent.indexOf('Mac') >= 0) { win_ie_ver = 0; }
if (navigator.userAgent.indexOf('Windows CE') >= 0) { win_ie_ver = 0; }
if (navigator.userAgent.indexOf('Opera') >= 0) { win_ie_ver = 0; }
if (win_ie_ver >= 5.5) {
document.write('<scr' + 'ipt src="' +_editor_url+ 'editor.js"');
document.write(' language="Javascript1.2"></scr' + 'ipt>');
} else { document.write('<scr'+'ipt>function editor_generate() { return false; }</scr'+'ipt>'); }
// --></script>
Change
http://www.yourdomain.com/htmlarea/ to the location where you've uploaded htmlarea to. It might be case sensitive, so be careful typing it out.
Find your entry area code, it looks like this:
CODE
<td colspan="2" width="100%" valign="top"><textarea<TMPL_IF NAME=AGENT_MOZILLA> cols=""</TMPL_IF> class="width500" name="text" rows="<TMPL_IF NAME=DISP_PREFS_SHOW_EXTENDED>10<TMPL_ELSE>20</TMPL_IF>" wrap="virtual"><TMPL_VAR NAME=TEXT></textarea><p>
Right after that
tag, add this:
CODE
<script language="javascript1.2">
var config = new Object(); // create new config object
config.width = "100%";
editor_generate('text',config);
</script>
Save and you're done!
