DBUtils - ExecuteHTML Error

I have the following 'simple Query' that pulls all records out of a table (table1) and displays them in the Webview (View_Tickets)


However I get the following error when I compile

Compiling code.
Error compiling program.
Error description: Missing parameter.
Occurred on line: 511
View_Ticket.LoadHtml(DBUtils.ExecuteHtml(SQL1, "SELECT * FROM table1", Null, 0))
Word: )

I cant see the issue re the missing parameter -
