Field content as parametres in a function

I have come across a puzzling behavior when trying to use the content of a field as parametres in a function, and I am trying to understand why.

I put the following in a field called «test»: 1,2,3,4,5

When I then call the function like this:  
		answer testFunction(field «test»), the paramCount() returns 1

If I use the values directly in the script: 
		answer testFunction(1,2,3,4,5), the paramCount() returns 5 as expected

I will also get the expected result if a do the following:

		put "answer testFunction(" & field «test»  & ")" into tScript
		do tScript

I guess the reason for this is that in the last example, LiveCode compiles the content of the variable tScript before execution, and that this turns what is first treated as a single block of text into a list of parametres. 

The reason why I want to understand what is happening is that I am about to teach my students how to write reusable code that will behave correctly for any number of parametres. 

So my question is if I am on the right track?
