I guess you got no answer because no one understands your question (well, I for sure don't ;-)
btw, conditional formatting is just that: formatting. To conditionally display text markers, you may want to add these markers as text objects to the layout and apply Conditional Hide (Hide when …) to them.
But first you (and we) need to be clear about what conditions you want to codify … so please try again!
Thank you Erolst.
It is a huge filemaker database. I was suppose to apply exact conditional formatting specified.
Finally, I was able to manage it.
What version of FM are you using?
I wouldn't use fields for this. Fields are for data. I would use a text object and the "Hide" option. Put the "!" on the layout and hide it until the condition is met.
Thank you for your response. It was my mistake. It clearly says that "add field". I was suppose to just add new field on the layout which already had ! as value.
I am very new to file maker and going through learning process so it was my misunderstanding about it.
