Modifying hard-coded values to Input variables breaks thinkscript

This should be easy, but it's been years since I've "thinkscript-ed" and I currently "lost in the weeds".

I have this that works:
#
declare lower;

plot halfpipe = .5;
halfpipe.AssignValueColor(Color.RED);
halfpipe.SetLineWeight(1);

I've made the input "halfpipe" an input variable and assigned it with an initial default value
#
declare lower;
input halfpipe = .5; # Assign initial default value

#Here, where I want to plot it, thinkscript complains by highlighting in the background of the "halfpipe" variable in all three spots:
plot halfpipe;
halfpipe.AssignValueColor(Color.RED);
halfpipe.SetLineWeight(1);

With these complaints that I don't understand:
Identifier Already Used: halfpipe at 35:6
Can not call AssignValueColor on halfpipe at 36:1
Can not call SetLineWeight on halfpipe at 37:1
Value never assigned to halfpipe at 35:6

... wtf, I did assign and initial value

I've tried it without assigning and initial value, I've tried placing both () & [] around "halfpipe" but no joy.
What am I missing... I know I'll feel real dumb after someone points out my "obvious" mistake..
Cheers

can declare a variable only once.
the variables declared by def, input, plot need to be different.
numbers are plotted by assigning a value to a variable name (that isn't previously used)

Code:
input halfpipe = .5;
plot z = halfpipe;
z.AssignValueColor(Color.RED);
z.SetLineWeight(1);
#
