Form Field (Number) and linked Custom Field (Number) failing to convert to currency w/ automation

[Melissa Shandy]

Jira Newbie here:

Working in a form, there is a number field (Display Name "Amount") that is linked to a Custom Field (also a number field. Field Name is "Wire Amount").
When a number entry is made to the Amount field, I am attempting to format it to a currency display value such as "$123,456.78"

The first thing I find odd is when I configured the custom field and selected it to be a number, I did NOT have a "dropdown option" to select currency as a value as Jira instructions state (see screenshot). When I attempt entering any number in the default value of the custom field, I get an error (also attached).

I attempted this automation as a workaround:
When: Work Item created
Range is 'A, B, C, or D' (<--these are radio button selections for different criteria)
Then: Edit work item fields
Chosen Field to set: Wire Amount

From here I have tried numerous JSON entries and all either produce an error, or, come back with "No Actions Performed" in the Rule's audit log. 

Some attempted entries are:

{{issue.Wire_Amount.asCurrency("en_US")}}.

{{issue.Wire_Amount}} $

{
"fields": {
"customfield_XXXXX": "1234.56"
}
}

I welcome any and all suggestions. Thanks!

Hi @Melissa Shandy 

Welcome to the community.

You can set a default for the field that is not a number.

In your automation, do a re-fetch action before doing the edit action on converting the number to currency.

Then you will need to have a text custom field where automation can set the number value as currency

So this field needs to be on the screen.

Then edit this field in the automation, like {{issue.<text-custom-field>.asCurrency("en_US")}}

So my linked custom field needs to be edited to a text field? Or are you meaning I need to create a new, separate custom field as text and add to the screen?

I attempted inserting the re-fetch between drawdown range and edit work item. The rule now states 'success' in the audit log.....but the field isn't updated at all. Still displaying without currency format.
