When does the hyperformular calculate its value

Tags: #<Tag:0x00007f0b10d8cee0> #<Tag:0x00007f0b10d8cd78>

hi, I have a cell that calculates its value from two other cells:
This issue, is when the user enters a value in E1 that is not a valid number (i.e. enters German comma instead of an English decimal value).
I fix this, by adding in my ‘beforeChange’ a function that returns a valid number. e.g.:
2,3% --> 2.3%
But the hyperformular calculation shows the error: ‘#VALUE!’.
Where am i going wrong here plz?

Hi @daniel.adams

Thank you for contacting us. Can you please share your current implementation? It would be easier to debug it this way.
