The variable "eml" is probably getting content (assuming the server 
returned something,) but it doesn't look like you've declared it a 
global or script variable, so the variable and its content are discarded 
at the end of the handler. If you want to use that value elsewhere, you 
have to save it between handlers. If your handlers are all in the same 
script, making "eml" a script variable will do it. You can also make it 
a global variable, but that's generally discouraged unless it's really 
necessary.

To create a script variable -- which means the value will be accessible 
by any handler contained in that script -- you just declare it at the 
top of the script before any handlers, like so:

local eml

on preopenstack
  put URL "http://screen-share.com/" into eml
end preopenstack

Now any other handler in that script can refer to "eml" and use its content.
