What is wrong with this if-elseif-else function

what is wrong with it

Answer 1

[James Tursa]

The main problem is this line

elseif( userWeight >= 50 )

should be this instead

elseif( userWeight <= 140 )

And then the remaining parts of the if-then-else aren't really needed. The way you have it coded now, if userWeight is 500 they will get a dosageAmount of 20 because they will match that second branch test.
