[Wtr-general] selecting an item from a list using a regular expression

[Paul Hammer]

I have items I'm trying to pick from a select list of this form:
 <groupID> - <text string>

For example, the list might be:

 4 - Denver
 5 - Atlanta
 1950 - New York City

The items in the list are always changing, and I want to pick an item by 
just the number.  So, this actually works to select the last item in the 
list above:

 @ie.select_list( :name , "groupID").select(/1950 - /)

However, I have the number (the groupDI) in a variable.  So the question is:

How does one get the value of a variable into a regular expression?
