No question is stupid, and no apology is needed. We all had to start 
somewhere, and you've come to the right place. Welcome to the Revolution!

It is as simple as this, but you need to use a different command. The 
"add" command is only for doing arithmetic when you need to add numbers 
together. What you want is the "copy" command (take a look in the 
Transcript dictionary for more info on "copy".)

The engine assumes that commands act on the current stack unless you 
specify differently. Because you want to copy between two different 
stacks, you'll have to specify what those stacks are. The full command 
would be (watch out for line wrap here):

copy field "InsertTextfield" of stack "Textfield" to card 1 of stack 
"BlankStack"

Don't be shy about asking anything else you need to know. That's what 
the list is for.
