Second dbjoin giving issues

[bespokeappstt]

I have a field element on listA and created a dbjoin to it on listB. I now want to create another dbjoin to it on listC. I keep getting the following error on listC when I hit 'Save and Close'


Is there some rule on creating 2 dbjoins from same field in listA?

Okay so the second dbjoin is not woking when I choose the 'Multi Select Dropdown'. I am able to attached the second dbjoin to listA if I choose the 'Dropdown' for render as. So is this a rule of sorts? You cannot do multiple, 'Multi Select Dropdown' for multiple dbjoins? Or am I missing something?
Here is the field element on the first list,


Here is the second list that is joiniing to this field element with multi select dropdown:


And here is where I attempt the second dbjoin on the



For the second dbjoin, if I choose 'Multi select dropdown' I get an error that was originally posted. Is there a way to implement the second 'Multi select dropdown'?

Maybe an issue with your element name ending with _

It's complaining
a_warehouse_repeat_vendor_po
is missing, the multiselect repeat table is usually created as
your-main-list_repeat_your-dbjoin-element name, so in your case I assume it should be/look for
a_warehouse_repeat_vendor_po_

In general your list and element names shouldn't start or end with _.

Yes, the '_' was the problem. Thanks. Solved.
