Index/Match to Create a Grid

Guess it my week for questions. :) Trying to figure out how to create a grid with "x" indicating a match of names and dates. It's a duty assignment schedule for clarification. The attached has a sample, but I've been playing with

=INDEX($E$1, MATCH(1, ($J3=$F$3:$F$18)*($L$2=$G$3:$G$18),0))

It seems to work in the first cell, but then when a name repeats I get a Ref# error. Other variations give me the N/A error. Looking for a nudge in the right direction and as always I appreciate the help in learning how to do new things!

WHH3

Try this: =IF(SUMPRODUCT(($E2=Table1[Date])*(F$1=Table1[Dir])),"x",)

That seems to work in the sample data, except that it appears to skip ever other row. I pasted in the first cell and dragged the formula if that matters. Going to tinker with it and hopefully figure out why; confirm cells, etc. Screen shot attached and THANKS!!!!

Wow, thanks John. I wasn't aware there was a difference in dragging (other than references changing like n2 to n3) and using the copy/paste function. Thanks for education!
Also, thanks to Raul for getting me started down the right path!

Whh3 - Solved!

Yea, if you fill the formula with Ctrl+Enter there should not be a problem.

I was not even aware that dragging changes the formula...what the...
But then again, for over 12 yrs. now, I am avoiding Tables in Excel altogether as I find it's behaviour beyond very basic stuff completely random and illogical at times xD
