When it comes to error handling, there are discrepancies between the work package description, figma and the Stage.

Here is a list of them:

1. When there is a mathematical error, I see this in figma:


<img class="op-uc-image op-uc-image_inline" src="/api/v3/attachments/806590/content">

On Stage I see:

<img class="op-uc-image op-uc-image_inline" src="/api/v3/attachments/806591/content">

2\. When I enter some text which is not int or float in administration part of the calc value, I get:

**Formula contains invalid characters.**

But in the wp description, there is this error:

**Only numeric values, project factors, calculated values and mathematical operators are allowed.**

Begin of the insertion3.End of the insertion Begin of the deletion 2\.End of the deletion In case of a circular reference, I get this on Stage:

**Formula contains custom fields that are not allowed:&nbsp;(Name of the other field)**

In Figma, there is:

<img class="image_resized op-uc-image op-uc-image_inline" style="width:556px;" src="/api/v3/attachments/806594/content">

### What is the expected behavior?

1. Specification (work package description and figma) and implementation should be aligned. If one of them is incorrect, we should have it corrected for transparency and clarity.
