Formula with array (ctrl+shift+enter) BUT with variable ranges... can anyone help me pls?

Hi everybody... not very familiar with the syntax of formulas and arrays (the "ctrl+shift+enter" ones). Here's my problem.

Got a formula =MATCH($W2&X$1,$T$2:$T$620&$F$2:$F$620,0)... basically it combines the values in column W and row X (hence the ampersand) making it a uniqueID and looks such ID inside the combined values from columns T and F (again, I'm using the ampersand to match the ID). The output of this formula is meant to be copied in a range as an array (the "ctrl+shift+enter" stuff)
>> BTW, I found this in another post from "mmmarks"... kudos to him for the excellent idea!!

Here's my problem... how can I make the formula as an array (you know, F2 then ctrl+shift+enter) and still make the cells within the formulas as variables and changing according with the cells??

In other words, within the formula above the $w2&x$1 is meant to change from cell to cell once the array is complete however, everytime I copy the array formula it fixes the w and x to a single value throughout the whole array (and therefore, the formula gets funky)

Can you give me some light here?
thanks!!!

thanks Vlady... however, even if I don't use any "$" at all, after I shadows the array range, then do the "F2 and ctrl+shift+enter", the whole array gets filled with the same formula.

Let me explain it differently... if the formula in the cell where I do the "F2 then Ctl+Shift+Entr" is MATCH($W2&X$1,$T$2:$T$620&$F$2:$F$620,0)
... I would expect the formula just under it to be MATCH($W3&X$1,$T$2:$T$620&$F$2:$F$620,0)
... and the formula to its right to be MATCH($W2&Y$1,$T$2:$T$620&$F$2:$F$620,0)

Perhaps I'm not understanding how the arrays work... can you give some input??

Thanks!

Please check the attached file. Although, I included some explanation notes... let me know if I omit anything.
Thanks much in advance!!

martindwilson THANKS !!!

so, it was a matter of creating the array in the first cell and only then fill it across and down... it worked, thanks much!!!

now I know better about arrays,

nice... thanks!!
