You’re asking Thunkable to do a math problem: “Subtract 03/16/21 from 4.” Even the best calculator isn’t going to know how to answer that.

You should Google date calculation Thunkable to get started with solving this tricky issue.

It’s hard to debug one block. Are you setting an image’s picture to a url? That should work fine, as long as the url is actually a picture.


yes, mam
so basically user using photo library block they are gonna select a pic and using that we need to get the image source. SO basically the image should be shown ,its showing the URL

so do we need to use javascript for the same?
