First, the Active Query Object. How are your results being out put on the results page? Many method uses frameworks and/or page builders, and with these, you really do not have access to the data you need. Instead, the page the outputs the results must be using a PHP template. So, you fist need to describe to me the Display Results Method that the form uses, and any other useful infomartion.
Second. I am not aware how this can be done, but, again, if you are using a PHP template, you MIGHT be able to do this.
This post describes how to retrieve the data from within the PHP template of the results page:

This will require intermediate PHP coding skills.
