Automate a click

Hi I am trying to automate a click on a webpage inside of a iFrame named (applicationsFrame0) with an id of "applicationsFrame0", inside this frame I am trying to click a link in a list that has a (<a title="EQUIP ALTRIGREEN" ) and a ( id="Citrix.MPS.App.jdo.EQUIP0020ALTRIGREEN" ).

I've tried getElementById("Citrix.MPS.App.jdo.EQUIP0020ALTRIGREEN").click()
but I get an AttributeError: 'NoneType' object has no attribute 'click'

any help would be appreciated. Thanks

There might be a function somewhere up the chain for which an intended
return specific_object
statement was forgotten and the function returned the default of None instead.
