"A valid expression must be set for parameter" error in Advanced Query Editor

"A valid expression must be set for parameter" error in Advanced Query Editor

  
In Community Edition, using Advanced Query Editor, I added  an input parameter and chose appropriate data type. But I get "A valid expression must be set for parameter" error .
Hi Raj

Can you elaborate?

The most comon reason for this is to define a parameter as date and then try to test the query using "YYYY-MM-DD"

If this is the case try passing #YYYY-MM-DD#

Let us know

Cheers
