Ok, up to now everthing works with my RegExp:

^[a-zA-Z]+[- a-zA-Z]?[a-zA-Z]+$

I can enter:

the cat
the-cat

but not:
the cat sat
the-cat-sat

I need to modify the above RegExp so you can have Spaces or "-" WITHIN a sentence BUT not in pairs or more, only by themselves

i.e.

the-cat-sat
the cat sat

NOT:

the--cat-sat
the cat sat

Thanks in advance.

Lrnmore,

If I use your RegExp:

/[^a-zA-Z\s-]|(\s\s)|(--)|(\|(-\s))/g

it works fine, but when I try to use your expression in ColdFusion it works fine as well but if I enter:

word$&*word word, it lets me enter that too, why wont the RegExp work in CF the same as it does in JS ?

Thanks.

It will not allow me to put word--word.

Here is the entire page. Try it out -

<HTML>
<HEAD>
<TITLE>Reg Exp</TITLE>


<script type=&quot;text/javascript&quot;>

/*
No double spaces or double - (&quot; &quot; or &quot;--&quot;)
*/

var reg = /[^a-zA-Z\s-]|(\s\s)|(--)/g;
function A(a){
var str = a;
if(str.match(reg)){
alert(&quot;bad char&quot;);
}

}
</script>



</HEAD>

<body>
<form><input type = &quot;text&quot; onblur = &quot;return A(this.value);&quot;></form>
</html>

Mark,

I see your ? about CF, don't know, but the string is still
not getting to you correctly...
Try this reg exp in cold fusion.

Code: 
var tststr = /[^a-zA-Z\s-]|(\s\s)|(--)|(\s-)|(-\s)/g;
[code]
One Last Time

It works fine like I said, but it allows me to enter:

word$£^$%^&^word

why does it let me enter any old crap in between the words ?

This only does this in CF, not when it is running as a HTM page with JS !

Did you use this last string:

var tststr = /[^a-zA-Z\s-]|(\s\s)|(--)|(\s-)|(-\s)/g;

There is an open &quot;(&quot; in the one you indicated you were
using. The &quot;(\|(-\s))&quot; in the first string could be the problem.

yes I used the last string.

As I said works fine in a JS app but not CF ?
