How can I get the value of a dropdown node to output to text?

I'm trying to make a selection software, with the value of the dropdown being the price of the labeled item, and I want the actual value to print to a text so the price can be shown and totaled. I've tried using the function nodes to get the value and return it as a new message but I can't seem to get it to work.

It would be helpfull if you provided a simple variaton of your flow showing the problem. As it is, no one but you knows what you have tried or what your code looks like and that makes it hard to suggest a solution.

It's also helpful to provide the versions of NR, node.js and the dashboard (you can get these from the startup log)

NodeRed v.2.2.2
Node.js v16.14.2
Dashboard v3.1.6

I've tried to just directly connect to a text output, as well as write a function that takes the message and turns it into a variable to try and print. This is where I'm at currently:

can you explain what buttons you push, which field you enter etc?

If I connect the output from your dropdown node directly to your text node, the selected value is displayed in the text.

So can you say more clearly what it is that doesn't work for you?

Apologies, I'd like t have that text value then print to a seperate sheet with all the values, like an "add to cart" function. Id also like some of the values to be multiplied based on the selected quantity
