OpenURL and targeting frames question.

I have been unable to set the target attribute to the name of a frame in the OpenURL() statement and have it successfully load my frames.

Are the only two options 'current window' and 'new window'? I hope not.

openUrl("http://creator.zoho.com/ensobase/home/form-embed/Task_Manager/DealPreLoadHidden=" + input.Deal, ("dealInfoTarget"));
