Well.. the reason ur getting an error is because u are comparing a 'string' variable to an integer value. So u are basically saying

if "dogs" < 3    which doesn't make sense.

U need to determine how many letters are in the word and then compare that to the value u want. I'm not really sure how to do that.. maybe try using char?

The solution to your problem lies in your processing section. The function length(), which returns the length of a given string.

your code:

 if name < 3 or name > 24 then 


As you where told, this is checking a string var to an integer.  This dosn't make sence.  You need to find the length in letters of your word, to compare it to your ints (aka. allowable length).


if length(name) < 3 or length(name) > 24 then


this "length(string)" checked the length of your string var, and returns the number as an int.   This will allow you to check it.
