Empty and logical expressions

[Ralph DiMola]

Mark,

Same wrong result on 5.5.1, 5.5.2 and 5.5.3 on XP SP3 and 5.5.1 on MacBook
10.6.8
When using the message box!!!!!!!

When it is in compiled code.... no problem, works as expected.

It still sits at the top of the bite-an-LC-newbee list.

Thanks for checking it out for me!

Hi Ralph,

I tried it and I get **.

on mouseUp
     TestItems 1,  ,2
end mouseUp

command TestItems svar1 , svar2 , svar3
     put "*" & item 1 of svar2 & "*" --> "**"
end TestItems

Which version of LiveCode do you use?
