when you are running my prg, after you enter your name and rank. then select south for the direction then the prg closes and says Variable has no value. What does that mean. here's my code

code:

thanks for the help.

becuz u didnt do the if statement for south,west,n east.....all u did is north
so then it'll skip the part of getting "answer", which leads to the "variable has no value" problem since the user couldnt enter values for "answer"

case structure is recommended

[Delos]

Your 'if direction is north' statement preceeds your 'if direction is south' statement. Thus, your programme will check for 'answer' before it has been entered, and thus it does not exist yet.

You really need to tighten your code here. Have you heard of 'elsif's? If not, read up the tutorial on ifs in the Tutorials section.

Ah! Beaten to the reply!

beat ya by one min.....lol

[the_short1]

how is this sposed to work anyways....

code:

elsif     %The Wizards Abilities.         rank = "wizard" then

shouldn't it be.,,..

elsif rank = "wizard" then
%The Wizards Abilities.

cuz urs is an incomplete if statement cuz it cuts iff afta % symbol....

yea.... CASE contruct works good... although i havn'ed used one in AGES!... i should start again..

[gamer]

use case instruction instead when it'a available, since it takes up less memory so the program wont lag as much overall
