Enter Parameter value

[irslan rafique]

Hi,
I am trying to create a report, filtered on a combo box(txtname).
This combo box is having a list of names.
I have one query(mainquery ) based on a single table(maintbl).
I created a blank form(GenerateRe port) with abovementioned combo box(txtname) and a simple button, which will open a simple report.
In mainquery, under names column i am defining the criteria:

[Forms]![GenerateReport]![txtname]

Result:
Report is being filtered accurately.
But when I open query i receive error 'Enter parameter Value'

The screenshot of error is being attached here.

Early guidance will be highly appreciated.

Thanks

The related form need to be open first in order the query to get the value from the form
