Hi Mkoslof, Thanks for your reply about my problems. However, i don't know why it cannot display the checkbox and uncheck box ??? The following is my code of a formula field. I tested field1 is true by output some normal text but it cannot output Chr(254) and chr(168) ?? why ??
if {filed1} = true then
formula = chr(254)
else
formula = chr(168)
end if
if {filed1} = true then
formula = chr(254)
else
formula = chr(168)
end if
