<div>
or something like this<br />
<br />
=iif([PredictedFEV1]=0,0,n<wbr />z([FEV1],0<wbr />)/[Predict<wbr />edFEV1])
</div>


or something like this

=iif([PredictedFEV1]=0,0,nz([FEV1],0)/[PredictedFEV1])

<div>
Excellent! &nbsp;Fast response thank you.

<div>
some more suggestions:<br />
<br />
=iif(a=0 or b=0, 0, a/b)<br />
=iif(nz(a,0)=0) or nz(b,0)=0, 0, a/b)
</div>


some more suggestions:

=iif(a=0 or b=0, 0, a/b)
=iif(nz(a,0)=0) or nz(b,0)=0, 0, a/b)

Re:  Microsoft Access Formula

Web Components are a set of standards currently being produced by Google engineers as a W3C specification that allow for the creation of reusable widgets or components in web documents and web applications. The intention behind them is to bring component-based software engineering to the World Wide Web. The components model allows for encapsulation and interoperability of individual HTML elements. Support for Web Components is present in Chrome and Opera and is in Firefox (with a manual configuration change). Microsoft's Internet Explorer has not implemented any Web Components specifications yet. Web Components consist of 4 main elements: Custom Elements, Shadow DOM, HTML Imports and HTML Templates.

Web Components

Microsoft Office is an integrated suite of applications that includes Outlook, Word, Excel, Access, PowerPoint, Visio and InfoPath, along with a number of tools to assist in making the individual components work together. Coding within and between the projects is done in Visual Basic for Applications, known as VBA.

Microsoft Office

Microsoft Access is a rapid application development (RAD) relational database tool. Access can be used for both desktop and web-based applications, and uses VBA (Visual Basic for Applications) as its coding language.
