VBA For Multiple INDEX MATCH In One Column

Basically, I want a code that does a simple index-match function for a column - But for all the #N/A's that come up in that column, I'd like it go to another INDEX-MATCH function - and another after that. I'm trying to keep it all in one column.

Here is an example of the first index match

=INDEX([FILENAME.XLSX]DealerDetails!$A$2:$A$15000,MATCH(L2,[FILENAME.XLSX]DealerDetails!$CJ$2:$CJ$15000,0))

If this turns out an #N/A, I'd like those #N/A's to switch to this formula:

=INDEX([FILENAME.XLSX]DealerDetails!$A$2:$A$15000,MATCH(M2,[FILENAME.XLSX]DealerDetails!$CK$2:$CK$15000,0))

Then the remaining #N/A's to go to this one:

=INDEX([FILENAME.XLSX]DealerDetails!$A$2:$A$15000,MATCH(G2,[FILENAME.XLSX]DealerDetails!$G$2:$G$15000,0))

The column I'm referring to will have around 2,000 records or less.
