Exit Loop On Criteria

I have a table named INPUT and a unique list named MODELLIST. I am doing a find function for each model from the modellist to the table input. I am using a autofilter to sort data and find to collect column data. Some models from the modellist may not be present in the table input. how do I check first if there is any data and exit loop if true. The following is part of the code that I am using and the error that is displayed is NEXT without FOR

Dim rFoundIt As Range
Dim iLoop As Integer
For Each model In Worksheets("sheet2").Range("modellist")
Worksheets("input").Activate
Selection.AutoFilter Field:=3, Criteria1:=model
With Sheets("input").Range("input")
Set rFoundIt = .Cells(1, 1)
For iLoop = 1 To WorksheetFunction. CountIf _
(Sheets("input").Range("input"), model)...............
