I have a system which has a dialogue that opens when the user wants to add a particular type of record (which is a list of clients). This dialogue window enables them to search for particular clients and add the specific ones they want. Once they've made their selection they need to click a button that will close the dialogue and pass their selection to the calling window.
However I'm wondering what the best phrasing would be to illustrate this. Currently I have "Add Clients and close' as to say 'You're going to add the clients you've selected to the original window, then close the dialogue'. But then I started thinking that maybe this was a little confusing and perhaps users might be worried it could close the whole program. I'm a little unsure about the ambiguousness of the phrasing.
We're only a small developer company so have no official designer, we do everything ourselves and I've little HCI experience. Is there better way of writing this or am I over-thinking it?
