Displaying a number went wrong

Hi,

I’m new to Dynamic Components and have been trying to slowly build up a desired DC for a few days, tackling each new problem one at a time. This time however I don’t know what I did wrong…

As you can see in the screenshot above, the number is displayed with a lot of decimals.

Changing the distance from 102 mm to 103 mm solves the display issue but isn’t the distance I need. Any ideas what I’m doing wrong?

Here’s the .skp
Dynamic Component - BRICK.skp (52.5 KB)

nothing wrong, just another bug
instead of concatenate, if you string with & , it works

Thanks!
