Test for Undefined Predecessor
Hello All,

I'm using a Formula - Work Date field called Start Date in my app. I want it to take:

1. the value of the End Date of any Predecessor that has been entered, or
2. the value of the Project's start date.

Everything is working as planned except:

if (isNull([Predecessor]),[Project - Start Date])

never ends up entering the Project's Start Date.

Conversely, when I enter:

if(isNull([Predecessor]),null,[Project - Start Date])

as the formula, it ends up putting in the Project's Start Date...I haven't entered a Predecessor and yet it is not null. Anyone know how to test if a Predecessor has been entered?

Thanks,
Eric

When you bring additional fields into a conversion, Quickbase often finds inconsistencies. For example, say you're converting your Companies column into its own table. One company, Acme Corporation, has offices in New York, Dallas and Portland. So, when you add the City column to the conversion, Quickbase finds three different locations for Acme. A single value in the column you're converting can only match one value in any additional field. Quickbase needs you to clean up the extra cities before it can create your new table. To do so, you have one of two choices:

  • If you want to create three separate Acme records (Acme-New York, Acme-Dallas and Acme-Portland) click the Conform link at the top of the column.
  • If the dissimilar entries are mistakes (say Acme only has one office in New York and the other locations are data-entry errors) go back into your table and correct the inconsistencies—in this case, changing all locations to New York. Then try the conversion again.
