Well thanks for pointing that out but it doesn't solve my problem. I'd like 
if someone could plug this code into IE5.5 and tell me what happens. It seems 
really simple. It gets to that line:

string = string.substring(0,indexOf("<TEXTAREA"))

it says function [objected expected char 1,. . .] at this line. I've tried 
using other variable names for "string". I've tried declaring preSTRvariable 
with a strict var preSTRvariable = new String() it always gets object 
expected.

code:

<html>
<head>
<title>Function Testing</title>
<script language="JavaScript">
function removeValue(string) {
if (string.indexOf("<TEXTAREA")) {
//line 17 follows
string = string.substring(0,indexOf("<TEXTAREA")) +
string.substring(indexOf("</TEXTAREA>",string.length))
return string
}
return string
}
function robot() {
preSTRvariable = document.body.innerHTML
preSTRvariable = removeValue(preSTRvariable)
}
</script>
</head>
<body>
<form>
<button style="background-color: #FFFFFF" onClick="robot
()">Click</button>
</form>
</body>
</html>
