Hi all,

I am trying to generate a random number and display this number in a label.

In the length label below, I would like to display the length of the randomly generated number from the variable.

Screen:

Link: [Project Link](https://x.thunkable.com/projects/6591710b5c4be931f6e8bec5/538bf9f6-2951-4879-92ff-28639cd25b10/)

The text in my “Length” label remains blank when I start this app and will not display the length of the variable string.

Strangely, this works fine if I make it read the length from the label rather than the variable but this won’t work for my purposes.

All help appreciated!

Hi,

Since an integer is technically a number, Thunkable needs it to be converted to text first become you can get the length.

There are various ways, but I just tried this and it works.
