Belows extension spreadsheet

[tim atherton]

Has anyone been able to get the bellows extension spreadsheet on this site to work?

Doesn't seem to be working for me....

Put in a new lens focal length and the calculations seem to all mess up

[jerry brodkey]

I couldn't get it tp work either in "openoffice".

The quickdisc right below it is a gem. Use it all the time.....

[Paul Butzi]

it seems to work for me using Excel 2003. Can you describe what goes wrong a little more?

[tim atherton]

jerald, I normally use the quickdisk, but the magnifications I'm using are giving a disk that's somewhat larger than the measuring stick...

Paul, my impression was you are supposed to be able to insert your own focal lengths?

So when I input say 250 instead of 300 I get #NAME? down the whole column from 250 onwards isntead of the new factors (only up to excel 2000 here)

Tim-

No, when I replace the '300' in E2 with '250', it just computes right down the column, no problem.

Would you like me to save a copy in some older version format, and email it to you?

And are you loading it directly by clicking on the link in the web page, so that excel loads to display the spreadsheet in the browser window, or are you saving it and then firing up excel to open the spreadsheet?

[tim atherton]

Hi Paul - I'm loading it up into Excel seperately

Maybe you could try emailing me a version saved for excel 2000?

done. let me know if it doesn't work.

[tim atherton]

well, still can't get it to work - I've tried three different computers with two slightly different versions of excel....

[Tom Westbrook]

I got the same error as you, Tim. I got it to display correctly by using the menu options: Tools/Add-ins... and in the dialog box checked off the "Solver Add-in". That was with Excell 2003 at work. Not sure if it works the same in older versions. The root casue seems to be not finding the function MROUND() in the usual places.

[Tom Westbrook]

Here is what Microsoft recommends about this problem. This didn't work for me, but may for you:

NOTE: The MROUND function is installed with the Analysis Toolpak add-in. To load this add-in after you install it, click Add-ins on the Tools menu. In the Add-ins dialog box, click to select the Analysis ToolPak check box.

I think you have to restart Excel to get the to update the sprteadsheet, but see support.microsoft.com/default.aspx?scid=kb;en-us;121730 for more info.
