Listbox showing blank items

Hello All

 

Wonder if anyone is having this issue or can help me get over it...

 

I'm using a conditioned Listbox, which values are extracted from Sharepoint Lists, depending on other Listbox selection.

The thing is, that this dependant Listbox is showing just blank values, as seen in the attached picture (I've selected some just to show you guys they are there) and it is curious because when I change the selection on the other Listbox, the one that this one is dependant of, it seems to change accordingly, but values still show as blank.

 

I'm using nested IFs to tell the Listbox which Sharepoint List to get the values from, as following:

 

If(Left(ListBox5.SelectedText.Value,4)="Heli",Search(Sub_Sistemas_HC,ListBox5_1.SelectedText.Value,"Title"),If(Left(ListBox5.SelectedText.Value,4)="Drea",Search(Sub_Sistemas_DC26,ListBox5_1.SelectedText.Value,"Title"),If(Left(ListBox5.SelectedText.Value,4)="ReCa",Search(Sub_Sistemas_RC3,ListBox5_1.SelectedText.Value,"Title"))))

 

Thanks for your time in reading and hope you could help me get this figured out

The biggest issue I see there is that you are using different data sources for each of your If statement.  This is going to return records that are different types from each list...definitely going to confuse the ListBox.

Is there any particular commonality between the lists that you are trying to display?  I assume Title...If so then you can consider a formula such as this:

 

Switch(Left(ListBox5.SelectedText.Value,4), 

  "Heli", ShowColumns(Search(Sub_Sistemas_HC,ListBox5_1.SelectedText.Value,"Title"), "Title"),
  "Drea", ShowColumns(Search(Sub_Sistemas_DC26,ListBox5_1.SelectedText.Value,"Title"), "Title"),
  "ReCa", ShowColumns(Search(Sub_Sistemas_RC3,ListBox5_1.SelectedText.Value,"Title"), "Title")
  )

This will give your listbox a common set of table columns (in this case Title) to work with and should produce better results for you.

 

I hope this is helpful for you.
