Hello Tornike,

Thank you for attaching the screenshots of the Layer Properties and Expression Parser dialogs.

Please try the following:

  1. For SQL Statement, click the drop-down and select Edit SQL Statement and the Query Builder dialog is launched.
  2. On the Query Builder dialog, under Fields, select the field that will participate in your expression.
  3. On the Query Builder dialog, click Add to SELECT.
  4. On the Query Builder Dialog, click OK and the Query Builder dialog is dismissed.
  5. For Expression, click the drop-down and select Edit Expression and the Expression Parser dialog is launched.
  6. On the Expression Parser dialog, do you see the parameter that you want to have participate in your expression?

Regards,

Dan
