ObjectGet question

 
Hi guys,
I want to get the retracements values for a fibonacci retracement object.
let's say the chart shows a downtrend, with higher high at bar 5, and lower low at bar 0.
I coded an expert with the following code:

----
ObjectCreate("fibo",OBJ_FIBO,0,Time[5],High[5],Time[0],Low[0]);
ObjectsRedraw();
double value = ObjectGet("fibo",OBJPROP_FIBOLEVELS+1)
----

my question is:
should "value" contain now the value for the 23.6% retracement?
if yes, why I'm geting value=0?
if no, what is wrong??
 
at first one question. what the levels You get when create fibo object manually?
Reason:
