Need a function or logic to sum all textbox values, where multiple selects where generated dynamicly, and has the same value, in jQuery

Question

I'm new to jQuery and dealing with the following, i need to sum all text input values (qtya + qtyb) or (qtyc + qtyd), where selected value in the first two columns with select input are the same value, which is the employee id.

for example, if i set select input with id managera1,managera3 and managerb14 to employee40, its value will be 40, so i need to sum (qtya1 + qtya3 + qtyb14) and display in stot40

same logic for plannera2, plannerb11, plannerb22 has employee46 is selected gtot46 = sum(qtyc11 + qtyd11 + qtyd22)

stot## = sum(all qtya##) + sum(qtyb##) where same value/person in managera or managerb is selected

gtot## = sum(all qtya##) + sum(qtyb##) where same value/person in plannera or plannerb is selected

Example of table: https://jsfiddle.net/monzi/68kt0m2h/10/

code:

<table>
<thead>
    <tr><td>managera</td><td>qtya</td><td>managerb</td><td>qtyb</td><td></td><td>plannera</td><td>qtyc</td><td>plannerb</td><td>qrtyd</td><tr>
