Auto copying cells between worksheets

Hello all! I know there has to be a simple answer to this, I just can't figure out how to do it. I have 1 excel file that has 2 worksheets within it. Basically what I need is some sort of formula or script that will auto fill sheet 2 with information that I type into sheet 1. Here is what I need it to do

The trigger will be Column K on Sheet 1 Y or N

Example:
If Sheet 1 cell K4 has a Y then copy the information from Sheet 1 A4, H4, & I4 to Sheet 2 A4, D4, E4
If Sheet 1 cell K5 has a N then copy nothing to sheet 2
If Sheet 1 cell K6 has a Y then copy the information from Sheet 1 A5, H5, & I5 to Sheet 2 A5, D5, E5
If Sheet 1 cell K7 has a Y then copy the information from Sheet 1 A6, H6, & I6 to Sheet 2 A6, D6, E6
If Sheet 1 cell K8 has a N then copy nothing to sheet 2
If Sheet 1 cell K9 has a N then copy nothing to sheet 2
If Sheet 1 cell K10 has a Y then copy the information from Sheet 1 A7, H7, & I7 to Sheet 2 A7, D7, E7

So I need to to copy information if the K column has a Y, but I need it to appear on sheet 2 all grouped 1 after the other. If you need more info I will try to explain better. Thanks!

In addition I have cells A2-K2 merged together as 1 cell and I would like that to auto fill in sheet 2 where I have A2 through f2 merged together.

Any help would be greatly appreciated! Thanks!

In Sheet2:

A4 should say =IF(Sheet1!K4="Y",Sheet1!A4,"")
D4 should say =IF(Sheet1!K4="Y",Sheet1!H4,"")
E4 should say =IF(Sheet1!K4="Y",Sheet1!I4,"")

A5 should say =IF(Sheet1!K6="Y",Sheet1!A5,"")
D5 should say =IF(Sheet1!K6="Y",Sheet1!H5,"")
E5 should say =IF(Sheet1!K6="Y",Sheet1!I5,"")

A6 should say =IF(Sheet1!K7="Y",Sheet1!A6,"")
D6 should say =IF(Sheet1!K7="Y",Sheet1!H6,"")
E6 should say =IF(Sheet1!K7="Y",Sheet1!I6,"")

A7 should say =IF(Sheet1!K10="Y",Sheet1!A7,"")
D7 should say =IF(Sheet1!K10="Y",Sheet1!H7,"")
E7 should say =IF(Sheet1!K10="Y",Sheet1!I7,"")

That should do it! :-)

Not sure about the merge problem though

Thanks for the quick reply!

If I am understanding this correctly, it would work to a degree.

This is assuming that the cells will transfer directly from a4 to a4, h4 to d4 , and so on. What if row 5 column k=N, will sheet 2 row 5 be left empty? Is there a way to make it print say row 8 of sheet1 to row 5 of sheet2, if sheet1 K5-K7 = N? Am I being too vague? Thanks!

P.S. I got the merged cells to copy between sheets, so that is no longer an issue. Thanks!
