Ben,
No doubt that was a brilliant suggestion...but since the "argvalue" passed
is dynamic, I cannot use that.Instead is there anyway I can use the argument
passed instead i.e "pass1.property"..that would serve the purpose..
I want the outputproperty to go into a static variable, as I need to use
that value later on....
Thanks
