Text Boxes using the same key?

I'm still learning, so bear with me if I'm making too many topics. <img src="smileys/smiley18.gif" border="0" align="middle" />

I ran into a problem where Construct 2 won't let me press the A key for initiating a text box, and then using the A key to close the text box. If I set the A key to open AND close, I'm pretty sure it's running the entire process all at the same time and thus makes it look like nothing is happening. If I set the keys to A for initiating and S to close, it works.

So, I've tried to play with values, hoping I can try to not confuse the engine so much, but I'm not doing so well with that. Can someone point out what I'm doing wrong here?

(And on a side note: if anyone knows where to find any info on making textboxes that scroll through individual letters as they output their words, like old RPGs, that'd be neat!)

edit:

Another thing I noticed is that I have two of the same NPCs in the same instance, but only the one in thelayout will perform the textbox functions. I'm not sure why that is. I was expecting them both to do the same thing.

I'd do a toggle thingy, something like this:

You'll want to have your open and close condition under same trigger, in your example they are under separate triggers (they are both 'true' if they are in the same button)

Ashley shows how to do it in one event.
