thank you for the points... Come to think of it, my formula may not be exactly what you want/ need:<br />
<br />
if you want to sum the first 12 non zero columns, than formula above is the way to go.<br />
<br />
if you want to sum 12 columns, starting from the first non zero value (and regardless of the value of those 12 columns, i.e. could be zero), than the formula is a lot simpler; type in B2:<br />
=SUM(OFFSET(B2,0,INDEX(MAT<wbr />CH(TRUE,C2<wbr />:xx2&lt;&gt;0,0)<wbr />,1),1,12))<wbr /><br />
(no array formula, replace xx with your last column)

<div class="content wysiwyg-content">
i have 300 rows<br />
<br />
each row has 12-60 columns of data in it, but each row has a different starting column . i need to create a new column, B, and put the sum of the first 12 columns with data into it.<br />
<br />
must ignore cells that have just a &quot;0&quot; in it.<br />
<br />
for example, row 25, has 0 in columns 12-34. So I need column B to equal the SUM of B35-46<br />
<br />
THANKS!

SUM FIRST 12 COLUMNS OF DATA FOR EACH ROW

Visual Basic for Applications (VBA) enables building user-defined functions (UDFs), automating processes and accessing Windows API and other low-level functionality through dynamic-link libraries (DLLs). VBA is closely related to Visual Basic and uses the Visual Basic Runtime Library, but it can normally only run code within a host application rather than as a standalone program. It can, however, be used to control one application from another via OLE Automation. VBA is built into most Microsoft Office applications.

Microsoft Excel topics include formulas, formatting, VBA macros and user-defined functions, and everything else related to the spreadsheet user interface, including error messages.

Microsoft Excel

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.
