Hi,

I am having participants estimate different amounts. I want their responses to be numerical and estimated to the second decimal point (e.g., 17.15). I cannot find a way to do this in Qualtrics with the existing options. For Content Validation I can specify numeric, a min, a max, and the max number of decimals (when really I want a min number of decimals). I maybe be able to achieve my goal via the Custom Validation with regex code.

Can anyone help me with this? Thank you!!

hi @ecw2144
You can use custom validation where the text entry matches with the following regex:
^\\d+\\.\\d\\d$
Hope this helps 🙂

Except Qualtrics doesn't recognize shorthand character classes, so you have to do it like this:
```
^[0-9]+.[0-9]{2}$
```

If it does, it must be something new. It has never recognized them before.

Hi ecw2144, I was searching for my questions about setting decimal places in my custom validation when I came across your post. I believe you know the answer to my question. Can you please tell me how to specify the max number of decimals for a numeric entry? I was able to specify the max and min of the range, but couldn't figure out about the decimals.

Thank you!
