enable fields for leads

dear all, can somebody help me with something very simple (i think). in my lead lay out i want some additional fields enabled (ones that are in the list of fields available so no custom field). How can i do this?



It is really simple to do.

thank you. found it! i have been fiddling with the drag and drop from toolbox to layout to get my leads layout sorted but the just don’t stay there if i drop. It is driving me crazy. any suggestion? seems more people have this issue in suitecrm but haven.t seen a solution yet. suggestions? regards, arnoud
