format painter does not copy the attribute of the field, in my oppinion and suggetion, Lets say you have 10 different fields
01.Duplicate your layout (only if you are worried about the old design just in case)
02.imagine your have field name f1 to f10
03.create conditional format for f1
04.delete f2- f10 fields
05.create copy of f1 field and dubble click the copy of f1 field, and select f2 field name from specify field window
There is a little trick to know here. Copy the element that has the conditional formatting. Then paste it on the layout where you want to apply it. Then make shure the element with the conditional formatting is on the foreground. Above all other objects. Then select the other object(s) and go to conditional formatting. Now you should see the correct formatting. Hit ok and the other objects should now be good. The trick is bringing the original to the foerground.
That's a good trick. You can also select all the objects and then specify the same conditinal formatting for the group all in one go.
