Hello guys, I'm facing with this problem:

I simply add a Numeric Entry Field and I would like to format it with 2 integer, so for example "06".

I try to play with the format property without success and then I also try to add at the value property the expression

```python
numberFormat({this.props.value}, "00")

```

but I have the error  
`Error_CycleDetected`

How could I manage this?

Thank you very much

You don't need to manually format the value of a numeric entry field.  
You can use the built in property `format: 00`

I don't know what I tried before. I was sure to have test it and cannot be able to make it works, but actually now is working. For sure it's my fault.

Thanks for your time.
