How can I use a field in the contraint message?

[DougBrowning]

I have a field where the constraint comes in from Collector.

I can use this field in a constraint no problem

.>=${GapMin}

But if I try to use it in my constraint_message here

       Gap length must be at lease ${GapMin} cm

I get this (it puts /formname/summary_info/fieldname

     

How can I use this number to make my constraint message flexible?

Thanks

Hi Doug,

Variable replacement is not supported for constraint messages at this time.  I've added this a potential future enhancement.
