Parameter type mismatch
■ A SUB or FUNCTION procedure parameter type does not match
  the DECLARE statement's argument or the calling argument.
 
■ Possible solutions:
 
  • Press F1 when the cursor is on the variable to display the
    variable's type; redefine type as necessary.
 
  • Compare the SUB/FUNCTION call with the applicable DECLARE
    statement and correct conflicts with defined parameter
    types.
 
■ If you need additional help, move the cursor to a keyword
  and press F1 to open the Help window.
