Messages in chat deploying too fast

[DomGurb]

I have an issue with the messages. I have a couple of bots 'talking' with each other in the beginning, and the deployment of the messages is too fast. I want to adjust the delay of the next message so it seems more natural as if someone was actually writing it.

here is the code for the delay:
<%
story.showDelayed("NAMEofPASSAGE");
%>

and I tried adding the amount of delay I want at the end but it didn't help.
<%
story.showDelayed("NAMEofPASSAGE", 5000);
%>
