Need help with a javascript

[K3JAE_John]

I want to add $3.00 to a field if a checkbox is checked.

If the box is not checked than the original amount entered is not changed.

EFS_FEE is the checkbox name

LUMPER_FEE is the textbox with a value - which could potentially be "0" or any number.

I've tried this and with no luck:

var Lumper = this.getField("LUMPER_FEE")
var Fee = this.getField("EFS_FEE");
if fee.value!="Off"
var Fee = 3
else
var Fee = 0
event.value = Lumper + Fee

Check the console for errors. There are many errors.

[K3JAE_John]

Yeah, the original content, I tried to fix but was not allowed.... latest update - still not working.

var Lumper = this.getField("LUMPER_FEE");

if (this.getField("EFS_FEE").value!="Yes")

var Fee = 3

else

var Fee = 0

event.value = Lumper + Fee

What's the calculation for this field, without the check-box?

I believe you only need to declare variables only once, so take away the "var" in front of, "Fee" and you only need to declare it a variable once. Also, make sure you are using open/closed brackets correctly,  https://www.w3schools.com/jsref/jsref_if.asp like so: if (Fee.value != "Off"){     Fee = 3; } else {     Fee = 0; } Also, make sure that, "Fee" is capitalised since that is how you first declared it, otherwise the script will not work, and put a ';' at the end of, 'var Lumper = this.getField("LUMPER_FEE")'

[K3JAE_John]

Check re-done code - Original copy was all full error and when I attempted to fix, system locked me out.

Most what you posted already was handled prior to your post. Thanks!

[K3JAE_John]

There is no calculation for the LUMPER_FEE. It is a hand input value by my drivers. I need to add $3.00 only if a specific case exists.

[try67 · Accepted solution]

That's a bit tricky to implement, but try this code as the MouseUp script of the check-box field:

var Lumper = this.getField("LUMPER_FEE");
if (event.target.value=="Yes") {
    Lumper.value = Number(Lumper.value)+3;
} else Lumper.value = Number(Lumper.value)-3;

[K3JAE_John]

That does not gonna work. Tried and I'm unclear on 1 thing:

     1: Why are you calling to subtract 3 if the box is not checked?

[try67]

Why are you saying it's not going to work before you tried it?

If you want, remove that part of the code and tick and un-tick the box several times and see what happens.

[K3JAE_John]

Apologize sincerely, I'm typing too darn fast and the meaning, now that I read, was not intended as it sounds.I did not mean I was not going to try it... I meant to say I tried, and it did not work. Too many irons in the fire and responding quickly got me.

[try67]

Maybe I misread what you wrote, but to say "it's not working" is not very helpful... What exactly is not working? Is the field not changing when you tick/un-tick the box? Is it changing, but not in the way it should? Be more specific, please.

[K3JAE_John]

Sorry, When ticking the box no change to the textbox amount occurs.

Current value in the textbox is $120.00

My intended goal (as I am sure you understand) is when the checkbox is ticked the value in the textbox should change to $123.00

[try67]

I understood the requirement.

Press Ctrl+J and check if there are any error messages in the Console.

[K3JAE_John]

The following is present:

TypeError: this.getField(...) is null

1:Field:Mouse Up

TypeError: this.getField(...) is null

1:Field:Mouse Up

[K3JAE_John]

OK, I figured out why the error on the NULL.. I did not originally have the '_' on the field LUMPER_FEE - just had a space.

However, with that being said, the problem, after correcting the field name, still is present where no change is made to the value on clicking the checkbox.

CTRL-J now shows no error now after field name correction.

[try67]

You need to tick the box, then check the Console window again. If it's still not working you'll need to share the file for further help.

[K3JAE_John]

How do I share the PDF file here? I only see a way to attach an image or HTML.

[try67]

You can upload it to something like Dropbox, Google Drive, or the Adobe Document Cloud and then post a link to it here.

[K3JAE_John]

Hopefully this works. This is a TEST file of what Drivers use in production.

Dropbox - PETS_LoadSheet_2019024-01.pdf

[try67]

You've changed the first line of code I've provided and thus rendered it incorrect.

[K3JAE_John]

Doh, Surely I did. I thought I made no changes. HOWEVER, having said that - that works as you figured.

I elected ot leave the 2nd portion of the code in in case I or the drivers mistakenly check it. Excellent and MANY Thanks.
