Ok, now I've got another problem here,  sorry about this! :(

this is another function that is similar

function DoPrompt(action,myTarget) {
	var revisedMessage;
	var currentMessage = eval('document.form1.'+myTarget+'.value;');
	if (action == "url") {
	var thisURL = prompt("Enter the complete URL for the link you wish to
add.", "http://");
if(thisURL!=null){
	var urlUBBCode = "";
var urlUBBCode = "<a href="+thisURL+"
onFocus='if(this.blur)this.blur()'>"+thisURL+"</a>";
	revisedMessage = currentMessage+urlUBBCode;
	eval('document.form1.'+myTarget+'.value+=\"'+revisedMessage+'\";');
	eval('document.form1.'+myTarget+'.focus();');
	return;
	}
}

This is only the top part of the function, after this come an else if with
almost the same piece of code, but that's not important right now...

Where I have var currentMessage 
eval('document.form1.'+myTarget+'.value;'); I am getting an error saying
"unterminated string constant"  any idea why this is?

		Cheers,
			Al.
