Find a sheet based on a cell name, then find the entry based on a different cell name, and fill in the values from adjacent cells - vba

Question

I'm pretty new to VBA, I've got a spread sheet that has a list of vehicle ID's in a row of columns, and different identifiers (ID) in column A.
So far I'm able to search for the sheet with the vehicle name and copy a range of cells to the main sheet. I'm trying to make it so that once it finds the specific vehicle sheet, it looks for the specific ID and pulls that in, rather than copy a set range of cells. I'm having it return nothing now, and when I had it before excel would crash, so I assumed I was in some sort of endless loop.
Dim ws As Worksheet, sh As Worksheet
Dim Rng As Range, c As Range
Dim ECU_Ovv As Range, ECU_V As Range
Set ws = Sheets("Overview") 'main worksheet to copy everything to
Set Rng = ws.Cells(3, 3).Resize(3, LastColumn) ' I;ve calculated LastColumn earlier, it's defined as a Long
Set ECU_Ovv = ws.Cells(5, 2).Resize(LastRow, 2)
For Each sh In Sheets
For Each c In Rng.Cells
If sh.Name = c Then
'Find row range for specific vehicle
LastRow = sh.Cells(Rows.Count, 2).End(xlUp).Row
Set ECU_V = sh.Cells(5, 2).Resize(LastRow, 2) ' this is the only syntax I could figure out to get it to let me set a range with a calculated variable
For Each ECU_Ovv In ECU_V.Cells 'now look for the ID in the specific sheet
If ECU_Ovv.Cells = ECU_V.Cells Then
a = ECU_Ovv.Value 'Put this here to see if I am able to match ID's from the main sheet to the specific sheet
'sh.Range("D12:D47").Copy Destination:=ws.Cells(24, c.Column) 'this was working but it's hardcoded so any change in the sheets would break it
End If
Next ECU_Ovv
End If
Next c
Next sh
I'm planning on adding a copy cell, 2 columns over (from the found ID) to the column of the vehicle (Rng), but I'll cross that bridge when I get there!
