I am trying to get variables to display on forms using the UI application form editor and in an expression field like:

Phone Number: ${form\_clientContactInformation\_mobilePhoneNumber}

The variable comes from another form. The result is:

Phone Number: ${form\_clientContactInformation\_mobilePhoneNumber}

I have tried combinations of #{} adding it as a form property connected to the variable etc. No luck.

There must be some secret sauce but I cannot find it.

Thanks

Chris

Hello @temecom, try putting only the name of the variable, without the reference to the form.

It’s what I have used and it has worked very well.

I hope I was helpfull.
