I am trying to change the body of the email which is generated by a custom SP2010 workflow. I'm using SPD2013 and I am able to get as far as the String Builder which contains the body text of the email. I've tried using %CurrentItem:ID% as well as %CurrentList:ID%. They both return a number, but unfortunately this number does not match the item ID number in the actual list. Not sure where this number is coming from...all I can think is I'm not referencing the correct source and/or field.
Any help is much appreciated...I'm new to SPD
EDIT:
Alright, so I've set the dropdowns accordingly (see above), but I still get a different number. I've also added screenshots of that, so you can see. Thanks for your help!

SharePoint List:
EDIT 2: Found the list which is bringing in the wrong ID number. Now I just need to figure out how to reference the correct list...since the workflow's associated list is not the list I want to reference.
