Good Afternoon

I shall be gratfeul if someone can shed some light on this.

I have a total figure in cell A33 (formatted as number, two decimal places) and I am tyring to multiply it by 12% and then round it to 15 mins. It seem to work, but only until 197.5 hours and anythinmg more than this total changes it to 00:30

The formula I am using is:

=ROUND(((12.07/100*A33)/24)*96,0)/96

Thanks
