Hello all,

I have a tab named "untitled" and a tab named "bluecard_homeplanaid".
I have data in tab "untitled" column "B". They're numbers such as
200906180333.
I need code to that takes the number in the first cell "B1" in tab
"untitled" and searches column "B" in tab "bluecard_homeplanaid". If found,
then that row in tab "bluecard_homeplanaid" would be deleted. This process
repeats for all of the numbers in column "B" in tab "untitled.

Note: The amount of data in column "B" , tab "untitled" changes daily.

thanks in advance!!!
