Send textbox to another page

Hello,

I want to send a 2 textbox to another page, but the other page displays for 30 seconds, then changes, but when I return to the same page, an error occurs.
I want to save the data inside the page itself so that when you refer to it, the data remains inside without a problem

please advice !!

From your description I did not understand, on which screen occurs the error? P1 or P3?

Try this

Use TinyDB
