dropdown

I need to calculate three values.

Depending on what we select in the drop-down list. So there is a choice in the drop-down list: “Amperage”, “Voltage” and “Resistance”.

In order to calculate “Amperage” I have to enter data in fields 2 and 3.

In order to calculate “Voltage” I have to enter data in fields 2 and 40.

In order to calculate the “Resistance” I have to enter the data in fields 2 and 3.

The functions solve these problems.

But in the “Results” field, you can somehow implement it so that, depending on what value I calculate, information appears in the field header that I have now calculated “Current strength” or “Voltage” or “Resistance”.

I have set this up, but it is when the calculation takes place, in the calculation header itself, that I need a caption to be displayed, depending on the calculation, that we calculated “Current strength, or “Resistance”. So far, I have only achieved the ability to display this in text mode. But it is precisely above the “results” field that there is a heading. It is static.

(function(){
var result = ”;
if( AND(fieldname2, fieldname40) ){
result = fieldname2/fieldname40;
jQuery(‘.text-here1’).html(‘Voltage drop on all LEDs – ‘+result+’ V‘);

} else if( AND(fieldname2, fieldname3) ) {
    result =fieldname2/fieldname3;

jQuery(‘.text-here2’).html(‘Voltage drop on all LEDs – ‘+result+’ Ohms‘);
}
else if( AND(fieldname40, fieldname3) ) {
result =fieldname40*fieldname3;

jQuery(‘.text-here3’).html(‘Voltage drop on all LEDs – ‘+result+’ A‘);
}

return result;

})()
