An array is a structure with a certain size. You can use dynamic arrays in vba that you can shrink or grow using ReDim but you can’t remove elements in the middle. It’s not clear from your sample how your array functionally works or how you determine the index position (eachHdr) but you basically have 3 options
(A) Write a custom ‘delete’ function for your array like (untested)
Public Sub DeleteElementAt(Byval index As Integer, Byref prLst as Variant)
Dim i As Integer
' Move all element back one position
For i = index + 1 To UBound(prLst)
prLst(i - 1) = prLst(i)
Next
' Shrink the array by one, removing the last one
ReDim Preserve prLst(Len(prLst) - 1)
End Sub
(B) Simply set a ‘dummy’ value as the value instead of actually deleting the element
If prLst(eachHdr) = "0" Then
prLst(eachHdr) = "n/a"
End If
(C) Stop using an array and change it into a VBA.Collection. A collection is a (unique)key/value pair structure where you can freely add or delete elements from
Dim prLst As New Collection
