Trouble updating database from form

I deleted my old post as I have made progress, and the old post was a little dumb on my part.

Site with form.

I have made some progress so I have edited the question.
I am having issues updating a database from a form.
CurrentRP ; input1
RPGoal: input2
So far only CurrentRP is updating.
Additionally, I would like to declare a new variable RPLeft and use the math function to find RPGoal-CurrentRP.

import wixData from ‘wix-data’; export function button1_click(event, $w) { let toInsert = { “CurrentRP”: $w(" #input1 “).value , “RPGoal”: $w(“input2”).value }; //let “x”= {$w(” #input1 “).value, //“y”=$w(” #input2 ").value, //“z”=(Math.round(y-x))} wixData.insert(“FormEnterRP”, toInsert) .then( (results) => { let item = results; } ) . catch ( (err) => { let errorMsg = err; })}
Thank You

It looks like a missing # sign

$w(“#input1”).value , “RPGoal”: $w(“[here]input2”).value }; //let “x”= {$w(“#input1”).value, //“y”=$w(“#input2”).value

I have the inputs now being sent to the dabase.
Now I am just having issues with the calculation and passing the calculated value to the database.

Any thoughts? Anyone?

import wixData from ‘wix-data’;
export function button1_click(event, $w) {
var begin = $w(“#input1”);
var end = $w(“#input2”);
var difference = (Math.round(end-begin));
$w(“#difference”) = difference; ← Parsing error assigning to rvalue

let toInsert = {
“CurrentRP”: $w(“#input1”).value ,
“RPGoal”: $w(“#input2”).value,
“RPLeft”: $w(“#difference”).value, ← here difference is not a valid selector error
};

wixData.insert(“FormEnterRP”, toInsert)
.then( (results) => {
let item = results;
} )
. catch ( (err) => {
let errorMsg = err;
})}

export function page1_click(event, $w) {
//Add your code for this event here:
}

I got it to work I think I was thinking it had to be harder than it was.
I did notice that these columns are added to the database as new columns.

export function button1_click(event, $w) { //the buttton on the page is not connected to the database

let toInsert = {

“CurrentRP”: $w(“#input1”).value ,
“RPGoal”: $w(“#input2”).value,
“RPLeft”: $w(“#input2”).value-$w(“#input1”).value , //<-- I was convinced I needed to use (math.round(…
};

wixData.insert(“FormEnterRP”, toInsert)
.then( (results) => {
let item = results;
} )
. catch ( (err) => {
let errorMsg = err;
})}

export function page1_click(event, $w) {
//Add your code for this event here:
