IF Expression Help

Summary

The IF Expression is not returning the else value I'm inputting

Content

Hello,

I'm trying to write an IF expression but cannot return a proper else value.  The following is my formula:

IF ([EMPL|CUSTOM_1321] == "Rosemount" or "Norpac" or "Septre" or "PIC" or "Farris")  [Spartan Acquired Years] else  0

I'm trying to show if the above companies are in a cell I want the value to remain else I want 0 to display.  Attached (in a Word document) is the Excel Formula and Report Output.

thanks,

Rachael
