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.

but when the teacher checked it she said it was right... but the thing is the errortrap part. 0.o?... i dont get it?

your code:

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).

code:

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.
