different action based on the number of times a button is pressed

Dale, the simple format of if is

if (condition)
{
code if true
}

In your case you need to put everything you want to happen "if true" within those braces:

...
  if (sensorValue > 100 && sensorValue < 200) 
   {
      set position
      rise code
      delay
      fall code                      
   }
   else if (sensorValue > 200 && sensorValue < 400) 
... etc

Keeping things indented properly helps you keep track of the braces. And the auto-format tool also. (on the Tools Menu)
