kscwgirl,
Did you remember to put the ! at the end of your VL_Data sheet name in the formula? So it should be VL_Data!
Looking at the picture of your data in Sheet1 and your explanation that the VL_Data! sheet has employee names in A:A and supervisor name in column B, this formula should work. Does employee name in Sheet1 match the name in VL_Data! exactly, if not you would be getting a No Match error tho'. Works on my sample worksheets....
Put formula in Sheet1 I2 and copy down
=IFERROR(INDEX(VL_Data!B:B,MATCH($A2,VL_Data!A:A,0)), "NoMatch")
Explanation of Index
=INDEX ( Column I want a return value from , MATCH ( My Lookup Value , Column I want to Lookup against , Enter “0” ))
