Solved: Combobox defaultselecteditems shows data selected in frontend but unable to return its ID

Hi ALL,

I have a combobox inside a gallery in which

gallery Items- is a collection which is SQL view filtered with some ID's.

combobox Items:

Sort(product_category,product_category_code)
 
combobox DefaultSelectedItems:{product_category_code:ThisItem.product_category}
 
Issue- It selects the correct value and also highlight the value as selected in frontend of powerapps using DefaultSelectedItems but when I try to find out the id of selected value it shows blank.
 
Any help on this please!
