Javascript function throwing error

[cvman16]

I've been banging my head on my keyboard over this for a few days now, and hoping someone out there can help me out. I'm not very expirienced in Javascript, but undestand the basics. What I have is a textarea in a form, that I want to test and give a warning if more than a set number of characters.

1. <script language="JavaScript" type="text/javascript">
2. <!--
3. function Test_Too_Long(element, maxChar)
4.    if (parseInt(element.value.length)>maxChar)
5.    {
6.        msg = "You have entered " + element.value.length + " characters.\n\n"
7.        msg = msg + "Please try to limit your post to less\nthan "+maxChar+" characters otherwise this\ncauses the page to run on.\n"
8.        alert(msg);
9.    }
10.-->
11.</script>
12.
13<form name="TradeBoardUpdate" method="post" action="trade_board_update.asp?v=<%=request("v")%>&post=true" >
14.<table border="0" id="overall" align="center" cellspacing="3">
15.<tr>
16.    <th>Asking for in return<br>
17.    <textarea name="return" id="return" cols="28" rows="8" onChange="Test_Too_Long(this, 250)"><%=objRec1("asking")%></textarea></th>
18.<tr>
19.    <td colspan="2" align="center"><input type="submit" name="Submit" value="Submit">
20.<input type="reset" name="reset" value="Reset"></td>
21.</tr>
22.</table>
23.</form>

So as it stands like this if I comment out line 4. the function works as it's designed (minus this line). When I uncomment out that line, once the focus leaves the text area, it throws a javascript error "object expected" for line 17.

Can you see something I should try?? Any assistance is greatly appreciated.

Hello Friend your code is good and working fine but needs a simple modification while checking in the If Condition please replace the maxChar by parseInt(maxCha r). since you are passing as a argument javascript will treat every parameter as a string so do this change your code will be a good one.
Post back if you have any doubts.
