Good day all, hope you can help!!

I need a formula that will take info from sheet A column b only if sheet A
column A contains "EMC" somewhere in the text. I need it to paste into Sheet
B coumn B exactly as shown in sheet A column b as well as index to the next
line that contains this info.

example:
Sheet A
A B
EMC, Safe PREPARE Checklist
ENVIR Send PCB for test
ID, EMC, SAFE Testing files complete

Sheet B:
A B
PREPARE Checklist
Testing files complete

I have tried using the following formula but I get empty lines "FALSE"
between the actual info and it is not pulling the information exactly as it
is on the other sheet. It is also not pulling all info from lines that
contain the EMC text. If EMC is listed as EMC, SAFE, ID, FW etc it does not
pull that line item.
=IF(Sheet!A6="EMC",Sheet!B6)

Help, what am I doing wrong? I am a newbie and have spent several hours
looking through all the formulas/discussions you have provided to other users
but did not see one that would do what I am looking for on this sheet.
Your help would be appreciated.

Thanks,
Trese
