?{Mod?|0} in a drop down macro

Note:  This is for 1st edition D&D .. so I am using Vince's 1st edition character sheet. I am trying to create a drop down menu for Attribute Checks (and Saving throws) and while I can get it to work correctly in a basic form, I would like to try and add the ability to have a Modifier entered due to various gameplay reasons. This is what I have so far for the basic Attribute Checks &{template:general}{{color=@{selected|color_option}}}{{subtag=Attribute Check}}{{name=@{selected|character_name}}}{{?{Attribute|Strength, @{selected|strength} Strength / Roll: [[1d20]] |Intelligence,@{selected|intelligence} Intelligence / Roll:  [[1d20]]|Wisdom,@{selected|wisdom} Wisdom / Roll:  [[1d20]]|Dexterity,@{selected|Dexterity} Dexterity / Roll:  [[1d20]]|Constitution,@{selected|constitution} Constitution / Roll:  [[1d20]]|Charisma,@{selected|charisma} Charisma / Roll:  [[1d20]]}}} I would like to add the Mod and have it added/subtracted from the roll that is made and display the result.    I have tried to add the Mod in there a few different ways, but anytime I do it breaks the drop down macro (assuming since it is also using the same type of code) Can anyone help me figure out how I can add it?    Thank you in advance

If you don't need Modifier to have its own entry (like {{Mod=?{mod|0} }}, this should be fairlly straightforward. But you''ll need to move the inline roll brackets. Something like this will avoid the need for any special syntax: &{template:general}{{color=@{selected|color_option}}}{{subtag=Attribute Check}}{{name=@{selected|character_name}}}{{[[1d20 [Roll]+ ?{Attribute| Strength, @{selected|strength} [Strength]| Intelligence,@{selected|intelligence} [Intelligence]| Wisdom,@{selected|wisdom} [Wisdom]| Dexterity,@{selected|Dexterity} [Dexterity]| Constitution,@{selected|constitution} [Constitution]| Charisma,@{selected|charisma} [Charisma] }+ ?{Modifier?|0} [Modifier] ]]}}

I am trying to do something a little different, but your post did make me realize that I was over thinking this.   The only thing I need within my drop-down is pulling up the characters current attribute for whatever one I am rolling on.   I do not need any of my rolls in there, I can have those at the end of the code.    Thank you
