MATCH function - unexpected #NA result

My goal is to solve this equation:
{=INDEX(Sales_Data,MATCH(C3&A5,SalesDataB:B&SalesData!AD:AD,0),41)}

The MATCH function is producing a #NA result.

When I use the formula wizard for just the MATCH function..

{=MATCH(C3&A5,SalesData!B:B&SalesData!AD:AD,0)}

..the wizard shows the formula result (row#) as 3,539. When I go inspect the table, in fact row 3,539 is the right row.

However, when I hit OK, in the wizarditself, it sheet shows the value as #NA.

I don't understand what is wrong with MATCH function. Is it the formatting of the cell?

Help is appreciated.

Thank you. However, that was just a typo on my part.

This is Salesforce data that I've pasted into an Excel tab called SFDC. Below are the actual two functions, again, where the MATCH is producing the #NA.

{=INDEX(SFDC_Data,MATCH(C3&A5,SFDC!B:B&SFDC!AD:AD,0),41)}
{=MATCH(C3&A5,SFDC!B:B&SFDC!AD:AD,0)}

and it works.

muchas gracias.
