[flexcoders] Sending parameters to server

[ilikeflex]

Hi 

I am sending request to the server. I am pasing parameters as shown 
below

params.action="<businessService><businessData><workLists>" 
+ "<worklist><month>2</month><year>2008</year></worklist>" 
+ "</workLists></businessData></businessService>";

params.action="<businessService><businessData><worklists><worklist><mont
h>2</month><year>2008</year></worklist></worklists></businessData></busi
nessService>";

In second case i do not get error but in the first case i get the error 
from server.I do not know what is different??

Any pointers please.

Thanks
