can you check for the fault event and see the Fault message and post it here???

you can follow this example also

http://blog.flexexamples.com/2007/10/29/passing-parameters-to-an-httpservice/

but I think their is nothing wrong in the way you are doing it, and you are getting a n/w exception. check the  fault message you will get to know better

Thanks for the reply, here's the error im getting, it seems to think im passing Hardware as a variable and not as a String

ReferenceError: Error #1065: Variable Hardware is not defined.
      at global/flash.utils::getDefinitionByName()
      at mx.utils::DescribeTypeCache$/describeType()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\utils\DescribeTypeCache.as:89]
      at mx.utils::ObjectUtil$/getClassInfo()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\utils\ObjectUtil.as:780]
      at mx.rpc.http::HTTPService/send()[E:\dev\3.0.x\frameworks\projects\rpc\src\mx\rpc\http\HTTPService.as:701]

Hi, sorry for the long reply ive been away on business:
Unfortunately that didnt work, this is what I did,
private var myObj:Object = "Hardware";
<mx:Button x="163" y="92" label="Search" width="199" click="findByType.send(myObj); "/>
 This produced the same error as before ????
Thanks for the help,, really appreciate it

NO Please try this directly

<mx:Object id="myObj" name="Hardware" />

else specify [Bindable] on top of the above myObject declaration. try and let me know.

hmm, i tried <mx:Object id="myObj" name="Hardware" /> originally but get a compile error stating (component declarations are not allowed here(note visual children must implement mx.core.ICIComponent))

So i tried declaring the object in the ActionScript area, ive now tried making it bindable and that didnt help either?

sorry there was a mistake, the way the http parameters are always passed in key value pairs

check this :), Please try that and let me know, I am outside on some business trip hence don't have my Flex installation for trying your solution , generally I provide full solution with code.
