Hello, I'm trying to set the estimated wait time in studio to speak back to the caller.  Right now I am just hard coding a value in ToExtVxml[1] as "ewt=100;".

I can see in the activity log that the parameter ewt=100 is in the log.  What I want to do next is to use say it smart to play back the number to the caller in an audio element, then play the prerecorded "minutes.wav".

I am using an app modifier to gather the data and storing it as element data, value is {Data.Session.ewt}

From there I move to an audio element and the data being {Data.Element.set_EWT.ewt} and would like to use the say it smart to play that number.

In the error log I see the following error.  I must be setting it wrong but not sure where.

Audio_01,element,warning,A substitution representing Element data from element "CVP Subdialog Start_01" and variable named "ewt" referred to non-existent information. An empty string was substituted instead.
