I have duplicated the “Browse Menu” Screen in the RTO app and linked the LFD to a different data source, which also includes a productGUI. The “Add” function on the LFD does not work anymore though.

What did I miss to update?

Hi,

You will need to update some code in the Developer Options \> Screen JS on line 47. You need to change the “Return to Office - Products” to the name of the data source the LFD is connected to.

Hope this helps,  
Deb

Thank you so much! I should have seen this…
