It has been a few years since I have really wrote any substantial amount of macros. This one is a few years old and I am trying to identify the issue and feel like it should be coming to me easier. I am hoping someone else with a little better knowledge base might be able to identify it easily.

The VBA essentially runs a quick set of calculations upon workbook open. I adjusted the location that it is doing this by one column which changed the range reference but not sure why this would have impacted its operation.

Runtime 1004 is showing up on the following line items from the code below. Based on my understanding it is most likely due to the reference of the text denotation of the column (i.e. "C" or "D"). What I am struggling with is why this is the problem as it worked before and what a quick fix would be.

Range("C" & r) = (A + B) * (C ^ D)

Range("D" & r) = (A + B) * (C ^ D) * F

Range("E" & r) = (A + B) * (C ^ D) * (E ^ dblPowerToE) * F

Code:

```
Private Sub Workbook_Open() Dim A As Long, B As Long, C As Long, D As Long, E As Long, F As Long, N As Long
Dim dblNetWorkDays As Double, dblEstWorkHrs As Double, dblHoursInDay As Double
Dim dblAvailHours As Double, dblPowerToE As Double
N = Range("A" & Rows.Count).End(xlUp).Row
For x = 4 To N
If Range("A" & x).Value <> "" And Range("P" & x).Value <> "" Then
dblEstWorkHrs = Val(Range("O" & x).Value)
dblHoursInDay = 8
If DateValue(Range("P" & x).Value) <= Date Then
dblNetWorkDays = Application.NetworkDays(DateValue(Range("P" & x).Value), Date)
dblAvailHours = dblEstWorkHrs - (dblNetWorkDays * dblHoursInDay)
Else
dblNetWorkDays = Application.NetworkDays(Date, DateValue(Range("P" & x).Value))
dblAvailHours = dblNetWorkDays * dblHoursInDay
End If
dblPowerToE = 1 + (dblEstWorkHrs / dblAvailHours)
'Lookup values from target row
Select Case Range("I" & x).Value
Case "Audit"
A = 10
Case "PHA"
A = 7
Case "Inspection"
A = 5
Case "Other"
A = 3
Case Else
A = 0
End Select
Select Case Range("J" & x).Value
Case "Regulatory", "Quantitative"
B = 3
Case "Corporate", "Semi-Quantitative", "External"
B = 2
Case "Site", "Qualitative", "Internal", "Any"
B = 1
Case Else
B = 0
End Select
Select Case Range("K" & x).Value
Case "Gap"
C = 3
Case "Requirement"
C = 2
Case "Improvement"
C = 1
Case Else
C = 0
End Select
Select Case Range("L" & x).Value
Case "Regulatory"
D = 3
Case "Corporate"
D = 2
Case "Site"
D = 1
Case Else
D = 0
End Select
Select Case Range("M" & x).Value
Case "0-6"
E = 5
Case "7-12"
E = 4
Case "13-18"
E = 3
Case "19-24"
E = 2
Case "25+"
E = 1
Case Else
E = 0
End Select
Select Case Range("N" & x).Value
Case ">$250,000"
F = 4
Case "<$250,000"
F = 3
Case "<$100,000"
F = 2
Case "<$25,000"
F = 1
Case Else
F = 0
End Select
'recalculate column C value in target row based on lookup results
If dblPowerToE <> 0 And A <> 0 And B <> 0 And C <> 0 And D <> 0 And E <> 0 And F <> 0 Then
Range("C" & r) = (A + B) * (C ^ D)
Range("D" & r) = (A + B) * (C ^ D) * F
Range("E" & r) = (A + B) * (C ^ D) * (E ^ dblPowerToE) * F
Else
MsgBox "Could not calculate. Missing or Invalid Parameter."
Range("E" & r) = "Error: Parameter"
End If
Else: Range("E" & x) = "Error: Date"
End If
Next
End Sub
