So I'm running into a couple problems with my program, it's calculating shipping time and cost using the weight and whether the package is international/domestic. Anyway, my problem is that I'm trying to error proof the weight input so that if someone puts in letters instead of numbers the program doesn't crash, but it's not really working...
put "And how much will your product be weighing? (In kg)"
loop %Weight Error Safe
get weightReply :*
%Weight Word Error Safe
if strrealok (weightReply)then
weight := strreal (weightReply)
%Weight Number Error Safe
elsif weight <=0 %Says variable not defined when letters in-putted
then
put "Input is not a number above 0."
exit when (weight >0)
end if
end loop
Furthermore, when you do put in a number, it doesn't continue with the rest of the program, it's just a bunch of blank space where you can enter more numbers.
