Set range using a variable for the row - Excel VBA

Short and (hopefully) simple question, I have searched a worksheet range to find a particular reference number and then want to search a range in that row for the first blank cell from the left, using the code snippet below (which I developed from this question: mrExcel help site)

Set projectSearchRange = Sheets("Milestones").Range("A:A").Find(projectref, , xlValues, xlWhole)

current_row = projectSearchRange.Row

Set searchrange = Sheets("Milestones").Range(Sheets("Milestones").Cells(current_row, 2), _

Sheets("Milestones").Cells(current_row, 23)).SpecialCells(xlCellTypeBlanks).Cells(1).Activate

milestoneduedate = ActiveCell.Offset(, 1).Value

However, the Set Searchrange line is throwing a

Runtime 424 - object required error

but as I understand it, I have written the line correctly.

Any insight as to what I've done wrong would be appreciated.

This should work for you:

Function MilestoneDueDate() As Variant

Dim projectSearchRange As Range

Dim Current_Row As Long
Dim SearchRange As Range

With Sheets("Milestones")
    Set projectSearchRange = .Range("A:A").Find(projectref, , xlValues, xlWhole)
    Current_Row = projectSearchRange.Row
    Set SearchRange = .Range(Cells(Current_Row, 2), Cells(Current_Row, 23)) _
       .SpecialCells(xlCellTypeBlanks).Cells(1)
End With


MilestoneDueDate = SearchRange.Offset(0, 1).Value

End Function
