Referencing an object via a project variable

Probably an easier way to do it rather than using Eval or complicated "if/then" logic, is for you to edit the NameMapping node for your browser process and set the browser name from a Constant/String to a Variable (see screenshot)



I would then rename your browser name mapping node and the corresponding Alias node from the specific "firefox" and "iexplore" to simply "WebBrowser".



Any calls then to your browser would simply be

Project.Variables.envBrowser = "iexplore"

while Aliases.WebBrowser.Exists

You can do the same for other name mapping nodes, components, and their properties.  See http://smartbear.com/support/viewarticle/12445/ for more info.
