How to evaluate whether a sub returned true or false

[easternfade 0]

Gday..

 

I am trying to do the following in a sub:

- check for various items on a page

- if not present, return false, else return true

 

I have tried to plug the sub into the qualifier part of an if statement, but it always seems to evaluate as true.

 

I also tried setting a variable with the Sub as the input, but Ubot gets an Invalid Cast Exception.

 

The video that's supposed to be on returning from subs is actually about error reporting, so I couldn't find any info there.

 

Hope that makes sense - I can post screenshots.

 

Any help greatly appreciated!

 

Thanks

This should do the trick...

Thanks a lot for that!

 

So then when I return #sub, do I just check the return value by using an If block in the main script? That's the bit I couldn't get right..

Yes, you need to run the sub and THEN have the if command see if whatever you want is true.

Thanks Hannah,

 

I haven't had a chance to try the suggestions yet, but do you mean I should set a variable with the result from the sub, or put the Run Sub call directly in the If statement's qualifier block?

 

Cheers..

It's late and I am probably doing something dumb, but I am having an issue trying to get past the error in the attachment.

 

I've also tried putting $return value straight into the if qualifier.

 

The contents of the sub being called is exactly the same as the example bluegoat posted above.

 

Any ideas?

 

Thanks!
