[las_users] Referencing LAS GUI Information

[John Schattel <john.schattel@xxxxxxxx>]

Hello All,

I'm trying to access the "Selected Depth" information that the user has 
selected in the LAS GUI.  How can I reference this information?  Is 
there a variable that contains the value of the user's input?
I want to be able to insert the "Selected Depth" value into the position 
currently occupied by "$2" in the script below.

Thanks for any suggestions you care to provide.

John
