Assistance with Creating my First Macro

Good Evening all,  I have been attempting to make my first power card macro and I am finding it very confusing, I have read so much nd have been trying but I guess I really do not understand how it is done.  I would like to make a Two Weapon Fighting power card macro and others, but this one first, I have been playing around with things and am just not figuring it out.  Could someone please assist with my badly started macro? !power {{ --desc|Two Weapon Fighting --format|Joxar --leftsub|**Main Hand** --rightsub|**Off Hand** --Main Hand|[[1d20+@{Joxar|strength_mod}]]vs AC }} I am trying to get my proficiency score added to this and the second weapon and am not figuring out how.  Also the title is not coming up, this is what I get with what I have If someone could offer me guidance I would truly appreciate it. Thanks Firefox1968

For something like this, it is always good to see if there is a thread for that specific api script.  If you check the api forum, there is an active thread about a quarter of the way down the first page.  If you don't get a reply here, posting there will be sure it is seen by people using that script.

Edit: seem you already go a more comprehensive answer on your API form post. If this is using the D&amp;D 5E sheet, the attribute name for the proficiency is pb , so [[1d20+@{Joxar|strength_mod}+@{Joxar|pb}]]vs AC should do the trick.
