Automating co-relations with help of framework, How it works ?

I have created a framework. In which I am trying to extract and replace the dynamic values mentioned below.

1. 123456
2. EX123456XY
3. EstimateID_EX123456XY

I want NeoLoad to co-relate 3rd value, 2nd Value and then the 1st value in this sequence. How can I achieve this. Otherwise, issues will arise due to one value is part of another.

How exactly the framework works in NeoLoad?
