Problems with count in Lazreport

[elidorio]

Good afternoon

I'm having a little trouble, to do a count on Lazreport for displaying quantities of rows returned in the group, as this marking in annex.
What am I doing wrong?

as a COUNT function parameter must specify only BandName, eg. MasterData1. See in the atachment.

Thank you very much paweld, it worked perfectly.
