How can I set the number of lines in a Data Report detail section of the report.

Actually I am having seven rows from a query, and it's more than one hundred that I use for each of the commands.

here's a snipet of the code:
SELECT * from tbl_entradas WHERE fecha = datevalue(now)

this is the SQL query, but I just obtain seven lines of this, and there is no way to fix this, none that I know, but you guys, can help me , for sure!


thanks!
