Hello,
I reviewed your article regarding "Execute SQL Server Stored Procedure With User Parameter In Power BI". Thanks for sharing it. I have a question regarding passing parameters in "m" that are text. I run the follwing "M" code which is largely based on the pattern you supplied in your example:  
  
When I run this code only the headers return.     
 
Is the declaration of the  "Clientname" correct by using "Text"? Am I using Text.from correctly? I hope this is clear. Please help!
