Thanks again,
I changed args to arg.
To keep it simple, I just want to use that arg parameter value
{"gender":"G0,G1","
agegroups":"A0,A2","metrics":"users,cpc_median","groupby":"country"} inside
my javascript function.
If I try to assign it to a variable like:
var k = arg;
It is giving undefined variable arg.
On the other hand,
If I am trying to access this variable passing as a third parameter to
function(v,k,{"",""})
It is also giving me error.
Please help me on the above.
Thanks,
Venkatesh
