Just use IsEmpty(table::fieldname) as your "condition" expression.
Or IsEmpty(Self), if you want to apply the conditionally formatting to multiple fields on the layout at the same time.
I've tried both of these with no result. The field still remains blank with no fill color.
Any other ideas?
Works for me, so the field you refer to in your conditional formatting probably isn't blank. Also, instead of [Formula is IsEmpty ( Self )] as a formula, you could use [Value is Empty]. Check for whitespace characters (spaces, tabs, returns, etc).
Also, are you using the "Conditional..." command from the "Format" menu, when a field is selected in Layout mode?
The field is most certainly blank. It is a calulation field, so it is not modifiable. I cannot add spaces, text, etc in the field.
I am using the conditional formatting from the format menu on the layout mode.
And when i put Value is Empty in the formula, it says that Filemaker cannot find the specifiedtable (error message)
Sorry about the misunderstanding, but when you setup Conditional Formatting, you have two main choices, 'Formula is' or 'Value is'. If you choose 'Value is', you then have another drop down that allows you to select from a list of options. One of those options is 'Empty'. Choose it, then, select a fill color from the area below.
