Test if Source Table is empty

[AllisterB]

Hi
I am trying to test if the Source table is empty before I do the transformations.

My attempt does work I get an error "Expression.Error: The import Changed Type matches no exports. Did you miss a module reference?"

The error has only occurred since I inserted the If then else piece of code.

What do I need to change ?

Thank You

let


    Source = Excel.CurrentWorkbook(){[Name="t_AccredoBranches"]}[Content],
    #"Test If t_AccredoBranches Empty" = if Table.IsEmpty(t_AccredoBranches) then "All values are null" else
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type any}, {"Column3", type any}}),
    #"Removed Top Rows" = Table.Skip(#"Changed Type",5),
    #"Promoted Headers" = Table.PromoteHeaders(#"Removed Top Rows", [PromoteAllScalars=true]),
    #"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"Code", type text}, {"Name", type text}, {"Inactive", type text}}),
    #"Uppercased Text" = Table.TransformColumns(#"Changed Type1",{{"Inactive", Text.Upper, type text}}),
    #"Added Custom" = Table.AddColumn(#"Uppercased Text", "Custom", each Text.PadStart(Text.From([Code]),4,"0")),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Code"}),
