I am getting a subscript out of range error with the following line, otherwise, it works like a gem...

I dont think that it can find the method .NZ....

If app.Nz(app.DLookup(field, TableName, "Cstr(" & field & ")='" & value & "'"), cNotFound) = cNotFound Then

Sorry, I missed your post somehow.

Nz() is definately a method of the Access application class -  you can verify this by a slight change in the code:
First, from the Tools menu choose Refernces and add a reference to the Microsoft Access xx.x Object Library (xx.x depends on the version installed)
Then, in the code change
     Dim app As Object
     Dim app As Access.Application

You'll then get Intellisense prompts on all the methods of the application object.

The only reason for declaring the variable as an object is that it then doesn't matter what version of Access is on any PC that the code runs on. Adding the reference ties the workbook code to the version in the reference.

The DLookUp() I coded will only work with Text fields in the table. If your target field might be some other type, e.g. Numeric or Date, you'll have to add logic to check the field type and format the third parameter accordingly.
For a string it's:
For a number the quotes must be left out:

I'm not sure how an Subscript out of Range error could be thrown
