Unable to compile some documents for deployment:
Program.ev3p: Use of a block which no longer exists.

The block I want to make. It will put a input value inside a given range. When I try to upload i always get a error. I already deleted every thing and started new. And always it will give me a error. The Lego software looks very buggy to me. Am I the only one that has these problems ?

This is the block i want to create

This is the MinValue block that gives the minimal value of two.


This is the MaxValue block that gives the maximal value of two.

And this are the blocks in my program, and there all there.

  • Can you upload the project so I can test it by myself? I've heard the error message before but I'm not quite sure what the solution was. Maybe if I can test with it there's a chance I remember the solution. Nov 9, 2017 at 19:44

Try exporting(saving locally) the block that shows error. Then delete it from the program and import it from where you saved it
