Help with adding a number by one increment with each instance of "reset button"

[trevor_b]

The answer I found here: 

https://answers.acrobatusers.com/Help-adding-number-increment-instance-reset-button-q96703.aspx 

was beyond my technical knowledge. 

I'd like to know first how to create a form reset button and then have it increment the previous number on save and close.

Where/how do I add the Javascript code?

Reset button: Add a button with the "Reset Form" command as its Mouse Up action.

Counter field: When do you want to change its value, exactly?

The basic code to do it is:

var f = this.getField("Counter");

f.value = Number(f.value)+1;

f.defaultValue = f.value;

Try67,

Thanks for your response.

I'm new to Javascript in Acrobat. I composed my form in InDesign including text fields and check boxes.and added a reset button which works well. Where do I add the script in Acrobat?

Ideally I would like to increment on save or some other suggestion that would allow me to have a different record each time.

I would use the Will Save event. You can find it under Tools - JavaScript - Set Document Actions.

Is it possible to add step by step screenshots? I am sure there are others who would benefit from this.
