The proper comparison would be 'if input1 = "a" then', as string constants have to be enclosed in double quotes > input "Feet amount: ", ft > > answer1 = ft * 3.2808399 Don't know where you got that number from but a foot in the commonly accepted Fred Flintstone units is 0.3048m (1 foot = 12 inches of 25.4mm each, that's 304.8mm = 0.3048m) > cls > print ; ft; " feet is equal to "; answer1; " meters." > sleep > > elseif input1 = b then Same as above, to compare strings, you need to enclose the string constant in double quotes, so it needs to be 'elseif input1 = "b" then', or else you again compare against an uninitialized variable named b > input "Meter amount: ", m > > answer2 = m / 3.2808399 Again wrong math, in order to get from meters you need to divide by 0.3048 (or multiply by 3.28084) > cls > print ; m; " meters is equal to "; answer2; " feet." > sleep > > end if > sleep > end > > >Any ideas? See above. It would be really helpful for you if you hit the books about BASIC (almost any one will do) to understand the differences between the different data types and how to use them.
