Trying to use If Statement

[Robnboard]

I am trying to get an If statement to separate a condition and display the value of Q. Using Apps Editor on the Ti-89 Titanium.


:If pumptype=0 Then
:Q=1.62e-4*(2*(liner^2-rod^2))*stroke*eff
:
:If pumptype=1 Then
:Q=2.43e-4*liner^2*stroke*eff
:EndIf
:EndIf
:Disp Q
EndPrgm

displays the letter q, doesnt appear to be solving for it with above inputs(stroke,eff etc...)

Do I need to be using some sort of return command, or solve function here?

[Boom]

I am going to assume that all the stuff after the 'Q=' is what u want to be solved and placed into 'Q'.

if so then place that 1st then a -> (found over 'ON') then Q.
if u want it to show the text itself then place the stuff before the -> in" ".

hope that helps you.
