I am fairly new to Mathematica, so I apologize if this question is very basic, but I was unable to find what I was looking for in other help documentation. What I am wanting to do is create a pop up menu where someone could select the temperature of water, then assign all the corresponding values of the water properties at the temperature. i.e.
PopupMenu[watertemp, {40, 45, 50, 55}]
Then based upon which temperature is selected assign the corresponding values to the viscosity, density, surface tension, etc. variables.
