Control Gallery Text Field with in Each Gallery Items using Check Box

[u4jaanus]

Hi All,

Working on an Ordering From which shows all products in a Gallery List, have a custom Text Field for Qty with default 1 with in Gallery List. Added a checkbox and want to make text field visible true or false with checkbox state. I am updating a variable on Checkbox state (check and Uncheck) however it changes the variable visibility for all items in Gallery. Need to restrict it to individual list item. Attached picture shows Qty text field showing for checked and unchecked list items, should be visible for checked list items only. Not getting any ideas. 

Any help plz.
