Hello Kyle,
One the things you can do instead, is to use the built in computation rule on Seblod.
Add the field Article Title as you normally would and make it hidden. Click on button 5 and on the Computation Rule column click Add. After the lightbox is open, on Computation field, choose the option Concatenate and on Fields, choose the fields to concatenate.
One downside for this solution, is that it does not have the separator option as on SD Concat, so, the title will be something like this "FirstLast", without the space in between names.
I'll suggest to implement this option for future release.
