如何基于同一行中的另一个单元格突出显示列中单元格值的所有实例？

Question

I am trying to use either CONDITIONAL FORMATTING or VBA to achieve the following.

Let's assume columns A and B
Column A contains a list of locations and are duplicated many times, eg. the location "ANYWHERE" could be in 20 different rows (but in the same column).
Column B contains a Vlookup code that results in a numerical value (including 0) or are blank.

I want IF column B contains a value that is NOT 0 to highlight ALL INSTANCES of the same location in column A (even if the value is blank or 0 in column B).

So if on row 300, there is a location 'ANYWHERE' and column B (for that row) has a value of '10' then highlight EVERY instance of the word "ANYWHERE" in column A (below and above).

I got halfway there with conditional formatting to highlight the value in column A for any value that is not blank or higher than 0 in column B, but I do not know how to highlight all instances of that value in column A.

Also, if in row 100, 'ANYWHERE' has a value of '20' in column B (and thus all instances of "ANYWHERE" get highlighted, and then in row 200 'ANYWHERE' has no value in column B, that instance of 'ANYWHERE' should NOT get UN-highlighted

The values in the first column should be highlighted based on the value in the last column.
In this case, everything with NM-5F-0335 should be highlighted

Here is the formula: =COUNTIFS($A$1:$A$12,$A1,$B$1:$B$12,"<>0")>0
