In MS Access:

In the query:
I set a input parameter: [Please enter the date:]

I run it, enter a parameter. The results come out, it is correct.

And then I sort the ascending order of the Vendor Name.
And close the query.

Second time, I run it, It give out 2 times [Please enter the date:]

I need to enter twice input. Why?
How can I solve it?

Please let me know, thanks.
