Forms :: Subform Always Shows First Record Based On Date

So, let's say I have a table named FLOWER_SHIPPING that has field:

Date [Date]
Flower_name [Short Text]
Amount [Long Integer]
Sender [Short Text]
Address [Long Text]

Then I created a form named MAINF with FLOWER_SHIPPING as its RecordSource. The form only has one TextBox: Date.

Then in MAINF, I created a subform named SUBF with FLOWER_SHIPPING as its RecordSource, in Datasheet View. It shows all fields in FLoWER_SHIPPING as it is.

The link between MAINF and SUBF is Date.

I want SUBF to only show record based on the Date chosen in Date TextBox in MAINF. So far, yes it did what I want. But with problems:

1) [SOLVED] SUBF does show record based on the Date I've chosen in MAINF's TextBox Date, but it ALWAYS ALSO shows the first record on the FLOWER_SHIPPING table. And the date in the first record always changed into the Date I just input in the TextBox Date in the MAINF. Automatically.

Example: I chose 6/22/2013, and there are 2 records with that date. the SUBF will show 3 records: those 2 records + the first row of FLOWER_SHIPPING with its Date automatically set to 6/22/2013.

2) When I chose a date in MAINF, I have to click everywhere in the SUBF so that it will refresh its content. Can I have it refresh automatically everytime after a date chosen?
