This is a standard 'smart label' for inverts. It is set for 5. Is there a way to have the fields that are not needed not show up without erasing each one, one by one?

You could use Expressions, where if the value is nothing, the expression can make the text size 0, otherwise make it the size you want. It's pretty slick.

How do you do that?

I think that would depend on how your are getting the Invert in the field. I have done a similar routine where I use Property Sets for this information within the label. I don't think the expression that @tcorey suggest will work in that case. Can you post a file (or pictures) on how your inputting the data in the field.

We take the shot as the rim elevation and put the invert measure down in the properties. The I(A)=' are hand keyed in to the point label style so I'm not sure there is a way without editing each label as I input the information.

Your using property sets that have an equation so that when you enter the MD data from the field the Property Set expression computes the invert based on the CogoPoint elevation and the MD data (CogoPoint elevation-MD). I used a similar method without the VB expression as our field crews used a worksheet for each structure and a pipe mic to compute the invert, so the math for on the worksheet where I entered it directly into the property set. Below is an example of what I used with all aspects of the pipe being described in the cogo point label to the right. This helped quite a bit as I was usually doing between 100-200 structures in a 1.5 mile topographic survey. I too would have to delete any inverts that didn't have the data entered. As in the case below I would delete items D-F since they had no invert information.

In thinking about this last night @tcorey might be on to something but I believe it would require revising the label style so that each property set was defined as an individual component in the label to an expression in the label that would determine if it displayed or not. I've used this method in drawings where I wanted to display the point elevations with different colors. But I'm not exactly sure how it would look if the expression. I'm thinking prehaps an IF statement would need to be added to the label expression that would determine its visibility.
