asterisk users - Aug 2006 - can not get ${LEN(VAR)} and greater than ">" to work for me

Hello all,
I am trying to test if the length of a dialed number is greater than 7.  When 
i use:
exten =>
1,n,GoToIf($["${LEN(${numdial})}">"7"]?dialout:nodial);
and I dial an 11 digit number i.e. 1 800 xxx xxxx
i get this in the console:
Executing GotoIf("SIP/xxx-xxx-xxx-xxx-006ca720",
"0?dialout:nodial") in new
stack

indicating that the number was not greater than 7.
if i use:
exten =>
1,n,GoToIf($["${LEN(${numdial})}"="11"]?dialout:nodial);
and dial the same 1 800 xxx xxxx
i get:

Executing GotoIf("SIP/xxx-xxx-xxx-xxx-006ca720",
"1?dialout:nodial") in new
stack
indicating that the length of number dialed was equal to 11 digits.
so equal to works and greater than does not?
Can any one see what I am doing wrong?
*  version 1.2.9.1

TIA
John M

Maybe string comparison because of the speech marks?

I'm guessing that you need to remove the quotes like this:
>exten => 1,n,GoToIf($[${LEN(${numdial})}>7]?dialout:nodial);
You know neither side of the expressions will never be empty so you 
don't need them. You might also try something like:
>exten => 1,n,GoToIf(${len({numdial:7})}?dialout:nodial)
or even:
>exten =>
1,n,GoToIf($["${numdial:7}"=""]?nodial:dialout);

Thank You Matt and Ira
The speech marks/quotes were the problem. 
Matt sorry about the earlier direct mail used R instead of L for the reply.
