Runtime error on reading from TinyDB

MIT App Inventor Help

Hi Freinds,
I am trying to save bithdays into TinyDB from my app and then display the saved birthdays in a List Viewer.

The blocks used are as attached, but we are getting a runtime error "The operation WidthPercent cannot accept the arguments".
Please guide me about what I am doing wrong.

Thanks,
SG

Right click anywhere in the blank space and click on download blocks to show them, we cannot say anything until you don't show all the blocks or send an AIA.

Also, change ListView1.WidthPercent to ListView1.Elements.

Thank you Mayank!
Adding the code ListView1.WidthPercent to ListView1.Elements ." fixed my error.
Thanks for your help
