formit is it possible to get fi.validation_error_message to display if Math hook fails

Hi,

I've got the math hook working in my form fine, but wondered if it's possible to trigger the placeholder:


As currently the message is only displayed in the math hooks placeholder:


Which is at the bottom of a large form, so want something at the top to inform the users of issues.

I could do something like


But that doesn't get triggered if a field doesn't validate and I don't want to put both as guess it could be possible both could then end up getting displayed

Any suggestions?

Thanks

B
