Default Value of a drop down from a variable

[Capuchino]

Hello, 

I am building an application where people can pre-save data from a form.  Data  are  stored in a Collection. If they want to copy an item they already pre-save then with a Variable I update the form with the existing value. 

The drop down Reporting Unit is the one I would like to be updated with VarCopy value on edit form. The "VarCopy.ReportingUnit" doesn't work in the Default formula.  Do you have an idea on how to solve this? 

the reporting unit is existing in the Variable I check: 

Many thanks in advance, 
Capucine

Hi @Capuchino ,

Please check if the value of the variable exists in the 'RepUnitPLanningGrp' column.

As the screenshots show, the Value 'C' is not in the 'Col1' Column, so it shows the blank if you turn on 'AllowEmptySelection'.
