Hi, I am new to Thunkable and am exploring Lists and List views, however, I am stuck and would appreciate help on the below scenario. This is what I am trying to achieve :
I have a ListView- Symptoms with the items - S1, S2, S3, S4, S5
When the user clicks on an item I want to store the item in a separate list - " Selected Symptoms"
However, before I add to this list I want to check if the item exists in the list and add ONLY if it does not exits, if it exists then it should get removed from the Selected Symptoms list.
Here is the logic I am following however this does not seem to work and I am seeing the items added multiple times and they are not getting deleted
Note: I have another listview L_Sel_Symp - to display the items from the “Selected Symptoms” list.
