How to create a STRING formula with app parameters

Hi,
So i am constructing a message that will be sent out to the user. the message function is fine only that i am struggling to make a sentence which will be :

Your order code for (params.amount) of (params.fuelType) is (params.orderCode).

What would be the correct syntax for my solution.

Set a variable’s value to formula.

“Your order code for” + params.amount + “ of “ + params.fuelType + “ is “ + params.orderCode

It worked. Thanks Alot !
Appreciate.
