[cisco-voip] CRA Changeing Value of Integer

[Voll, Scott]

I want to tell the user how many callers are in front of them.

I have setup my script and everything is working well.  I get the
position in que from ICD and it reports lets say 4.  My integer value is
now 4.  But I want to play a prompt that says, "There are 3 Persons qued
before you. Your estimated wait time is xxx Seconds."

So I play a prompt P[thereare] + LineInQue + P[personsEstWT] + WaitTime
+ P[Seconds]

So Back to the question, How do I change the integer value?  LineInQue
-1?  What is the syntax?

TIA

Scott
