Right what you want is a tick box option
if the tick box is true then text will appear on your report
So build your report first with all of the fields you require -
now add a yes/no option to your table - tie this to your form with a tick box
and a little bit of coding if tick box = yes then table yes/no option = yes/true else no
now put this tick box on your report properties visible .no
now you have a trigger on your report
in your report details properties its build or then code builder or build code
if tickbox = true then whatever txt field = true which will be something like
textfield.visible=true
and if tickbox=false then textfield.visble=false
end if might need 2 of these
that should do it
