Filter macro stops if result is blank

[aravindhan_31]

I have recorded the below macro for filtering the values in column 35 with Value contains "Canc" and then filter col B & C with blanks then fill in all the blank cells Col B & C as "To be Cancelled" and "Invalid" respectively
once this is done again the it filters in Column 16 with Credit and then fill in all the blank cells Col B & C as "Credit" and "Credit" respectively.

sub fill_blanks
Sheets("Unique").Select
    LR = Range("A" & Rows.Count).End(xlUp).Row
'Field 35
   ActiveSheet.Range("A1:AS" & LR).AutoFilter Field:=35, Criteria1:= _
        "=*Canc*", Operator:=xlAnd
    ActiveSheet.Range("$A$1:AS" & LR).AutoFilter Field:=2, Criteria1:="="
    ActiveSheet.Range("$A$1:AS" & LR).AutoFilter Field:=3, Criteria1:="="
    Range("$B$1:B" & LR).Select
    Selection.SpecialCells(xlCellTypeBlanks).Select
      Selection.FormulaR1C1 = "To be Cancelled"
    Range("$C$1:C" & LR).Select
    Selection.SpecialCells(xlCellTypeBlanks).Select
    Selection.FormulaR1C1 = "Invalid"
    Selection.AutoFilter
    Range("B1").Select
' Field 16
ActiveSheet.Range("A1:AS" & LR).AutoFilter Field:=16, Criteria1:= _
        "=*Credit*", Operator:=xlAnd
    ActiveSheet.Range("$A$1:AS" & LR).AutoFilter Field:=2, Criteria1:="="
    ActiveSheet.Range("$A$1:AS" & LR).AutoFilter Field:=3, Criteria1:="="
    Range("$B$1:B" & LR).Select
    Selection.SpecialCells(xlCellTypeBlanks).Select
    Selection.FormulaR1C1 = "Credit"
    Range("$C$1:C" & LR).Select
    Selection.SpecialCells(xlCellTypeBlanks).Select
    Selection.FormulaR1C1 = "Credit"
    Selection.AutoFilter
    Range("B1").Select

the code works fine if there are results for the criteria "Canc" & Credit
but if no results exists for any one then I get an error message on the line

 Selection.SpecialCells(xlCellTypeBlanks).Select

and the macro stops
the reason fo this is when there is no results there will not be any blank cells, so macro cant select.
how do I change this to work if no result just skip it and proceed with the next one.

Thanks for your help

i'm sure there are better ways, though i'm probably guilty of using on error resume next

you are right using on error gives loads of trouble

any alternate way...
