doubt in adobe forms

Hi,

like the way we use the program symbols in scripts i.e &KNA1-KUNNR&, the same way i guess we can use Angular brackets i.e {KNA1-KUNNR} in adobe forms to display the value of a variable..

but it seems procedure is somewhat different in adobe forms i think.. how to use that in adobe forms so as to display the value of a variable i'm not getting..

is anyone having any idea on this

thanks
