Ok, but my question is how to put the rule. The rule to show or hide the object is the existence (or not) of selection in a list. For example, I have a list with 3 companies. If no company is selected, I have to show a graphic, but if one or more are selected, I have to show another chart and never the two graphs at the same time.
Ok, I understand what you did ... but unfortunately does not help me yet ... you are showing the object according to the variable and you use an object action button to set this variable. My problem is how to identify (can be a variable) whether there is any selection made one a specific list. Example: I have a list object with 3 companies, one or more companies have been selected, show an object, if none selected, show another company.
Thank you, tested and really do what I need. But my problem now is another. I need to show a graph or the other, but when one of them does not meet the condition "GetSelectedCount (CompanyField)" it's still there, but a text showing that the condition was not satisfied and calculating overlapping the chart that I need to show. Can you help me with this?
