Starfinder Serum Macro

I have been trying to create a dropdown macro for use in my starfinder game. The problem as I see it is the {template:sf_generic} requires a {{r1name=}}and{{r1=}} input to display properly. I can do this for an individual Serum of Healing following: &{template:sf_generic}{{title=Serum of Healing}}{{r1name=Serum of Healing Mk I}}{{r1=[[1d8]]}} The problem I'm having is attempting to create a dropdown list {{?{Serum of Healing|Mk I, xxx|MK II,xxx| etc. You can't then input the {{r1name=}} and {{r1=}} because the macro doesn't like the additional ending curly brackets. I have tried looking this up but I can't figure it out. Any help? 

You can html escape the ending brackets (e.g. }), however, I'd really recommend using a chat menu instead. If you do decide to do a roll query for this, I would highly recommend using a macro mule instead of a global macro because the global macro editor will eat the html replacements when you open it and resave it. Now, all that said, I think you can actually handle serums without needing to go quite so complicated: &{template:sf_generic}{{title=Serum of Healing Mk ?{Serum of Healing Mk|1|2|3}}}{{r1name=Serum of Healing Mk ?{Serum of Healing Mk}}}{{r1=[[ [[1+{?{Serum of Healing Mk},0}>2*2+{?{Serum of Healing Mk},0}>3*3]]d8]]}}
