This Method Requires More Parameters than were Passed Error
You didn't pass all the required parameters to a method. Another possibility is that you passed the required number of parameters but did not separate them with commas.
Example
Passing the required number of parameters but omitting a comma
ListBox1.insertRow 2 "Chicago"
:
ListBox1.insertRow "Chicago"
Passing too few parameters:
In the following examples, myFunction takes two parameters and returns a Double:
d=myFunction(5,6) //correct
d=myFunction (5,6) //also correct
d=myFunction 5,6 //error
d=myFunction //also an error
d=myFunction (5,6) //also correct
d=myFunction 5,6 //error
d=myFunction //also an error
