Getting SSML tags to work

Hi. I wonder if anyone here can point out what I may be doing wrong. I followed Braden’s SSML tag YT tutorial but can’t seem to get, for example, the “whispered” effect working. When I test and get to that block I see a “Unable to fetch response” error and execution halts. When I remove that section of the Speech Block everything works. This is the snippet:

Thank you, Jones.
<amazon:effect name=‘whispered’>Sam Jones, is it? Clearly not his real name.</amazon:effect >

Thanks in advance. - Ron

SOLVED. The issue turned out to be that I’d included a carriage return (as you can see, after the word “Jones” and that just prior to the effect tag for some reason caused the issue. So, passing that gotcha along for what it’s worth.
