Offset a Single Cell Range then Autofill Range with Formula

[Shiseiji]

Hope this makes sense as my searches have failed.
I would like to start my Match with an Offset of a named range then Autofill the column. The Autofill is retaining the original Offset and not progressing from what is "C2" to "C3" etc. Is this possible?
Line of code is

 .FormulaR1C1 = "=IF(ISERROR(MATCH(OFFSET(ws_3Admin1_UserLogOn, 1,0), ws_3Admin_RngUserLogOn,0)),""Yes"", """")"

Only commitment is to the smartest quickest code & TIA.

Again, thanks!
