vRA - put custom text in the ASD form field description

Hi,

I want to put some custom text in a ASD Form Field. The text would be a string that is passed on to the presentation in vRO. I know the question was already asked on this forum, but I cannot find the thread:(

From what I remember, you had to put you string variable in a vRO presentation element, in the General tab. The variable had to be enclosed in brackets, similar to {this}. But this won't work for me, can someone please post the correct formatting?

Thanks!
