I'm having a problem in one of my forms, I'm getting a "done with error" and some fields in the form aren't working on IE due to a javascript error somewhere. I emailed the creator of the component and they said that there is nothing wrong with the component but something inside w a js file is causing the problem on other browsers.

/js/el.script.js
function equalHeight(){
makeEqualHeight ($('el-botsl').getChildren());
makeEqualHeight ($$(['el-content','el-col1-bot','el-col2']));
}

Avis >> Avis Cars >> scroll down to Group V and click "book car"

I hope someone can help me in here.

When loading the page in Firefox, Firebug tells me the following error:

$("el-botsl") is null


"el-bots1" does not appear to exist on the page. Also, it looks like it should be referenced as $("#el-bots1") to indicate it is looking for a dom element with id="el-bots1", not a tag <el-bots1>

Error: $("el-botsl") is null
