You have encountered what I regard as a rather confusing point in VBScript syntax.
When calling a function and assigning its result to something, you parenthesize the function's arguments: x = myFunc(1,2,3) But when you call a sub, you don't use parens: mySub 1, 2, 3 Now it just so happens that a single-argument sub call will accept parens anyway: mySub(1) and mySub 1 do pretty much the same thing. Well almost... Putting parens around a single argument forces it to be passed by value rather than by reference. So mySub(x) passes x by value, whereas mySub x can pass x by reference. This confuses people though, because you can see mySub(x) in someone's code, assume that means parens are acceptable, try mySub(x, y), and find out there's a hole in that logic. mySub(x), (y) would work, pointless though that probably is for most applications.

What's wrong with the line of code above. When looking at the mouse object Click method there are parentheses in the method's break down. Warm regards.
