using variable with "=" in expression

[Anonymous]

Hi, all,

In my case, I would like to display the currency symbol based on the currency code:

I am confused to using variable in case like below:

in script:

let vCurrencyCode='Currency'; // Currency is a field

set EUR = chr(num#('20AC','(hex)'));

set USD = chr(ord('$'));

And in my dash, in order to get the currency symbol:

the expressions must be like this:

$($(=$(vCurrencyCode)))

And expression like below dose not work:

$($($(vCurrencyCode)))

May I know why a "=" is needed? To change a string from $(vCurrencyCode) to a variable?  Then why

$(=$(=$(vCurrencyCode))) is not needed?

Thanks very much
