Creating multiple choice field that filters inputs based on input of another field.

Hello all,

     I am trying to create a field that filters inputs based on the input of another field. I currently only have one table in the app. I've tried to locate conditional formatting but I'm not sure if the issue is I only have one table and need to add a second with the relationships present. 

     Example:

      Field 1 Input "A" then options in Field 2 are 1,3,5
      Field 1 Input "B" then options in Field 2 are 2,4,6  

Thanks in advance for any input.
