Object Error

[Pookaroo85]

I am working in Excel 2010 and am trying to print a report from another tab only if a specific cell is within a specific range. When I click the 'Print' button I get "Run-time error '424': Object required" when it gets to my LOW and HIGH strings. I do not know how to fix this. Any clues would be appreciated.

Sub PRINT_SLURRY_Click()
 
    'Prints batch ticket from different tab
    Dim LOW As String
    Dim HIGH As String
    
    LOW = Application.WorksheetFunction.VLookup(Range("C7"), Sheet.TANKS.Range("A:D"), 3, False)
    HIGH = Application.WorksheetFunction.VLookup(Range("C7"), Sheet.TANKS.Range("A:D"), 4, False)
    
    If Range("C10") < LOW Or Range("C10") > HIGH Then
        MsgBox "Batch Size is not within range!"
    Else
        Sheets("BATCH TICKET").Select
        Application.Dialogs(xlDialogPrintPreview).Show
    End If
    
    'Clears contents in form
    Worksheets("FORM").Range("C7:C8").ClearContents
    Worksheets("FORM").Range("C10").ClearContents

    'Sets focus back to MAIN SCREEN tab
    Sheets("MAIN SCREEN").Select

End Sub

I figured it out. I changed...

LOW = Application.WorksheetFunction.VLookup(Range("C7"), Sheet.TANKS.Range("A:D"), 3, False)
 8.     HIGH = Application.WorksheetFunction.VLookup(Range("C7"), Sheet.TANKS.Range("A:D"), 4, False)

to...

    LOW = Application.WorksheetFunction.VLookup(Sheets("FORM").Range("C7"), Sheets("TANKS").Range("A:D"), 3, False)
    HIGH = Application.WorksheetFunction.VLookup(Sheets("FORM").Range("C7"), Sheets("TANKS").Range("A:D"), 4, False)
