Re^2: SimpleDialogBox wont work

<HTML>

Here is the line it is complaining about:
return if $self->{-finish} != 0;
I kinda of knew the $self->(finish) was not getting defined. but im not sure why. the module should read standard out and when the cancel button is pressed should define $self->{finish} as 1 and kill the dialogbox.

My advice is first, check out what Perl's notion of "truth" is; robin wrote a very nice tutorial on truth (# What is truth? (Curiosity corner) by robin) on it on this site. And then, as said by ptum, check to see if `$self -> {-finish}` is defined before comparing it to 0. Or try `return if $self -> {-finish}`, which may be adequate. emc	[reply]
