I am trying to write an IF/THEN statement than presents a dialogue box if the name field is blank. If it has a name is in the field, continue.

 

I assume you are asking in the context of a script, since showing a custom dialog is a script step (you posted this in the Conditional Formatting section which is irrelevant to the problem).

I also assume that the purpose of the custom dialog is to allow the user to add the missing name and not allow them to continue until they do. For this, you would do something like:

Loop
   Exit Loop If [ not IsEmpty ( YourTable::Namefield ) ]
   Beep
   Show Custom Dialog [ "A name is required." ; YourTable::Namefield ]
End Loop
# the rest of the script

You could make this more elaborate by giving them the choice to enter the name and continue or to abort.
