Progress bar ref mismatch

[jyang72211]

Hi all,

On the attachment, the BD on left called the BD on right.  Notice that I have a broken wire on left, and I don't understand why.  It says that there is a conflict in class.  Do any of you know why?  The intension of the left BD is to get the main VI reference and loop through each control and indicator on the front panel of that VI.  Would what I am doing just give me the conrols but not the indicators?  Thanks

You need to cast your reference to a more specific class of slide.

Your wire is of the more generic Control Reference (as seen by the class listed at the top of the property node) and you are trying to feed that into the slide reference (as seen by the reference control and the property node in your subVI)
