The formule, which generates this exception looks very simple:
&=&=IF(E{r}<>0, F{r}/E{r}, 0)

It takes values from columns where Smart Markers are. The most interesting thing is, that if I enter this formule in another cell I don't get such exception and formule works just perfect.

Any suggestions would be appreciated.

Hi,

Well, I have tested and used your smart markers dynamic formula i.e…, &=&=IF(E{r}<>0, F{r}/E{r}, 0) with the attached version/fix and it works fine without any issue.

Could you try it and let us know if it works fine.

If you still find the issue, kindly create a simple console application, zip it and post it here to show the issue. We will check it soon.

Thank you.

Hi,

Thanks for your help. Unfortunatelly this patch haven't solved my problem. Please find sample code and excel file attached which I hope will help you to reproduce bug on your side.

It works fine if I move formula from cell G2 to N2. Also it works fine if I remove grouping from first column. I hope it will help.
