I am trying to join three variables with a string to form new, longer string with "_" in between each part, I have tried the Camel book and am not getting very far, is this the correct (or close to) the correct syntax? 
$Launch.'_'.$Expire.'_'.$area.'_'.'description.asp';

[download]
In the end I want the final string to read: $Launch_$Expire_$area_description.asp as an asp file name. thanks, Bill
