Hello,

Is there any way to do a number check that omits false errors like

source : O2

target: oxígeno

Thanks in advance,

Antonio

Try to create a checklist entry such as the following:

Source `O2`

Target: `-”O2” -”oxígeno”`

Powersearch: on

Moltes gràcies, Òscar.

What I actually want to do is a global number check that does not flag false positives, for example diatomic or triatomic elements in the source: O2, O3, N2, etc. and targets with their names instead.

The current “Numeric mismatch” stops at all of those even if they are not real errors.

Cheers,

Antonio
