Hello all. I am currently working on a system that searches user input against values in a data table and spawns an actor class dependent on the contents of that codes associated data row. What I want to do is use a string in the data table’s row to define search results to select a class, or grab the name of an array of actor classes and compare them in a loop against the rows string. My problem comes in deriving those names in BP without other input. Does anyone have any recommendations for how I might go about doing this or alternative ways to do something similar? Any input would be greatly valued!

Here is a look at my data table with the relevant part highlighted. This part is meant to be used to search for a valid actor class.

I want to grab the array of object instances from the search menu of this and filter them to see if any have a name equal to the highlighted portion above. I am unsure what to look for in the BP browser to try to grab this array however and need help with that

Hello. I had a revelation after talking with a friend I did not know maps were a variable type. So I will resolve my own question fully here for reference to anyone looking to solve a similar problem.

First Document link

BP Maps Official Documentation:

> **[Blueprint Maps](https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Maps/)**
>
> Creating and editing Map containers, an advanced container type, in Blueprints, including an overview of this container's properties.

Here encased in red is where I put in the string variable for whatever i want to call the highlighted object reference selection.
