Cursor doesn't set at first col and row in text area, cannot validate it using value.length

ha mo, Colin Fraser, moody headmann,

The position of the cursor is irrelevant to the validation of a string.
I suspect the error lies with the use of the "value" property. Try
placing the string into a variable eg: 
    <form name="myForm">
    <textarea name="area51"> </textarea>
    var astring = myformname.area51.value 
    <input type="button" value="Submit" onClick ="validate(astring)" > 
then using something like 
<script><!--
function validate(astring) {
    var ok = false 
    var good="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
    for (var i=0; i<astring.length; i++) {
        if (good.indexOf(astring.charAt(i)) < 0) {
            alert('Sorry, you have invalid characters, please try      
            again'); }
        else {
            ok = true   
        }
    }
    if (ok)  {
          myformname.submit()
    } 
} 
//--></script>
The submission actually takes place in the validation function, which
may not always be the best way of handling this, and I currently have no
way of testing this submission, but it should work... 
Good luck
