I think you are getting the name of the table wrong. Is it a real custom table in Kentico?
You should use codename i.e.
All those macros
do return somehting:
P.S. Make sure that this a custom table in SQL i.e.:
I think you just trying access some table in your DB , but it it not a customtable in Kentico sense.
If you want to access form table it will be a different macro: dont remember how it was in 7 but this will work in 11:
{% GlobalObjects.BizForms["BizForm.TestForm"].Items.Count |(identity)GlobalAdministrator%}
