Revised JS (Shop-script engine)

You need to update the JS (Shop-script engine)

What do you want?
It is necessary to make qty change the value in 2 services (at the same time, regardless of whether they are included or not) - (Apply logo (1 color), Apply additional 1 color) on the corresponding qty
Example:
The user chose the circulation(qty) "100 pct", the value of the services changed to "from 100 pct";
The user chose the circulation "350 pct", the values of the services changed to "from 300 pct";
And so on.
Possible value of services range qty
Do99s 0-99
From 100 100 100 to 199.
From 200 200 200-299.
From 300 to 399.
From 400 400 to 499.
From 500 500 to 999.
From 1000 to 1000 to infinity


This should only be done in the Plastic Handles section, without affecting the rest of the sections.

Possibility of implementation? Cost? Timeline?
