Summary sheet to create multiple worksheets

Hello - I'm new to the forum and know next to nothing about VBA. Browsing through the threads here, I found a code that could help me at my job. However when I run it I receive an error message - Run-time error 13: Type mismatch.

Ultimately the macro does what I want it to do and can live with the error, but please help me to understand what went wrong.

Problems:
Besides debugging the code, how do I also get it to skip accounts that have the "Amount" field blank? If there is no amount to pay, I don't want the macro to create a new worksheet unnecessarily and to skip to the next account that might.

Sub Authorization_Sheets()
' This Macro creates the authorization sheets for each
' fund listed in the main spreadsheet
' if sheet doesn't exist already
Dim LR As Long, Rw As Long

With Sheets("Main")
    LR = .Range("A" & .Rows.Count).End(xlUp).Row
    
    For Rw = 2 To LR
        If Not Evaluate("ISREF('" & .Range("A" & Rw) & "'!A1)") Then
            Sheets("BankForm").Copy After:=Sheets(Sheets.Count)
            ActiveSheet.Name = .Range("B" & Rw)
            [B5].Value = .Range("A" & Rw).Value
            [B6].Value = .Range("C" & Rw).Value
            [B7].Value = .Range("D" & Rw).Value
        End If
    Next Rw
End With

End Sub
