Hi All i have an array Results as below:

[

  "Customer Name",

  "AAA111222DEF",

  "2"

]

I need to extract the first and last element and assign it to a new String CustomerName and CustomerID, can someone please suggest as i am new to this development.

@anshul ,

You can refer to a particular item of an array with:

variables('Results')[0] - first item from Results array ;

variables('Results')[1] - second item from Results array;

and so on ...

To set a value of CustomerName variable you can use either initialize variable or set variable action (depends of the scenario) and use as value the first element of the array: variables('Results')[0]. 

Hope it helps !

my question, where do i type this variables('Results')[0] ? in expression window? can you please explain in detail on typing this in which action or which window?

@anshul ,

Here is what I have in mind ... 

"where do i type this variables('Results')[0] ? in expression window?"

Being a formula you need to used add dynamic contents -> expression.
