Sub-Report Query SQL Based on Main Report Field????

I have a main report with a sub-report for which I need the criteria in the sub based on the Employee ID and Date fields on the main report.  I've tried the following to no avail  on the criteria line of the sub report query.

=[Reports]![MyReportName]![TxtEMPLOYEE_ID]
=[Reports]![MyReportName]![TxtDATE]

I also tried using the OnFormat/OnPrint Events of the Employee Header of the report to pass the Employee and Date fields to a form and use those for criteria.  This did not work as well.

Any ideas will be appreciated.

Thanks,

ET Sherman

You don't need the equals sign.

But have you tried doing this with the Link fields ... Master/Child instead?

Yes, also just tried with Linked fields .... for some reason same results (nothing) in the sub-report.  Although the Master table and the Child table will have multiple records for the same employee on the same date.

This report kind of combines two different process (or types of records) on one report by employee and date (different sections).

This is why I need the sub report based on the employee id and date from the main report.

Seems like the SQL for the sub report is firing at the same the the SQL for the main report.  I can manually put the criteria in but I need it to be dynamic.

I'm with MX, the easiest way to do this in a report is to use the Link Master/Link Child properties of the subform control.

NO POINTS PLEASE:
 
To do this, get rid of the WHERE clause (or at least the EmployeeID and Date portions of it) from the subforms RecordSource.  Then click on the subform in design view and in the Data tab of the Properties dialog, click on the "..." in either the "Link Master Field" or "Link Child Field" property box.  Select the fields that should match in the "Subform Field Linker" dialog box and click "OK".

Then you will have to go back to the current event of the main form, and get rid of any requery methods you were running against the subform.

Further note:

"When you specify more than one field or control name for these property settings, you must enter the same number of fields or controls for each property setting and separate the names with a semicolon (;).

Are the date fields in the two tables all just dates, or is one based on date only, while the other includes Date and Time values?

Yep, thanks MX and fyed ... you are correct.  

Originally, I was not looking at the Link fields option because I got side-tracked a bit thinking that with multiple records in both tables I would somehow end up with duplicates on the report.  Therefore, I went straight for the query SQL criteria based on the Employee_ID and Date.  That's not the case though and the Link fields option is the proper approach to accomplish this task.
