dynamically change iframe src

[sramey00]

i have a lnkbutton in a datagrid.
commandname = viewpage
commandargument =

http://(url)

when the link is clicked the datagrid onitemcommand is called
and i want to set the attributes of the iframe source to the commandargument.

if (e.commandname == "viewpage")
  iframe1.attributes["src"] = e.commandargument.tostring();

however a null reference exception occurs...
the walkthrough shows e.commandargument.tostring() has a value (

http://...)

but the error still states a null refernce occurs.
any thoughts as to what i'm doing wrong?
