Hiya

I have a an time expression calculation

interval(avg(ShoppingTime)/1440,'h:mm') - interval(avg(ActualShoppingTime)/1440,'h:mm')

I wish to if the answer is a minus, just show 00:00:00 and not e.g - 01:00:00

is this possible please

Try

=fabs(interval(avg(ShoppingTime)/1440,'h:mm') - interval(avg(ActualShoppingTime)/1440,'h:mm'))

- fabs() function returns the absolute value of x. The result is a positive number.

I think you will need an if-check like:

interval(if(avg(ShoppingTime) <  avg(ActualShoppingTime), 0,

(avg(ShoppingTime) - avg(ActualShoppingTime)) /1440),'h:mm')

May be this:

Interval(If(Avg(ShoppingTime) - Avg(ActualShoppingTime) <= 0, 0, (Avg(ShoppingTime) - Avg(ActualShoppingTime))/1440), 'h:mm')
