Recalcualte is time expensive

Recalcualte is time expensive

Hi,

I've a macro that copies contents from one sheet (A)  to another sheet (B).

Sheet A has a sum function that sums up the 15 rows that are being copied from Sheet B.
The row with the sum function in it is not copied from B.
The sum does not recalculate so I had to add a range.recalculate line into the code.
The range has 3 cells with a sum function in each.

This one line makes the macro go from less than 1 second to about 5-6 seconds.
I would like to have the recalculation take place without the very visible user delay.
Do you have any suggestions I can try?

Thanks,
Dennis
