ComboBox with wrong value or null value in Gallery

I have two tables.

First Table. Customers with two columns Name, IDCountry ie. Kim,001

Second Table Country.   ID, Description. ie 001,'USA'


I create a vertical gallery, set Customers as datasource and inserted two input text and 1 ComboBox.

I set

1st input box = name , fine, I can see Kim

2. input box = LookUp(Country,ID=ThisItem.IDCountry,Description) , Fine, I can See USA

3 combox1 =   value = Country, and I was not able to understand how to set  the Defaultselecteditems.

Indeed, the combo is always blank.



I tried inserting a second records in country 002, Canada and in Customers Pialla,001 and changed the defaultselecteditems in

Filter(Country,ID=ThisItem.IDCOUNTRY,Description) and the results was


The Input ltext is right and the combo box are wrong.


Someone can Help me, I will do appreciate. It seems that for the combo box ThisItem is not working as the input text.

Hi @GiuseppeFina 

The value of combo1 is going to depend what is the data source in your table. 

If for instance this column is a lookup field your defaultselect property must be a id, value like this: 


    Id: LookUp(Country,ID=ThisItem.IDCountry,ID)
    Value: LookUp(Country,ID=ThisItem.IDCountry,Value)


What value combox1 is going to have ? 


thanks for your quick reply.

As I wrote for the combox1  value = Country, so when I click on the combo box I can see all Values



I implemented your suggestion, (apparently It misses a comma),  but I still cannot see any displayed value in the combo.


my aim is to have the same value in the input box and in the combo. Now the input is correct the combo is blank.
