SUMIF formula

[dpaton05]

I have a spreadsheet with a table in it. At the bottom of the table is a field where the GST is calculated for entries in the table. The GST is 10% of the value. I had the following code in it that calculated the GST correctly:

=ROUNDDOWN(SUM(npss_quote[Price 
ex. GST])*0.1,2)

There are multiple types of services that are selected and they give different prices but all of them have the same GST applied to them. The only exception to this is if the Service column has "Activities" selected. In this case, they don't attract GST so if Activities is selected in the service drop down list, I don't want GST applied to that row. How do I write the formula?

Thanks,
Dave

Here is the formula I tried to put in but it says there is something wrong with the formula.

=ROUNDDOWN(SUMIF([Service],"<>Activities",[Price ex. GST]*.1,10))

Here is another formula I tried:

ROUNDDOWN(SUMIF(npss_quote[Service],"<>*Activities",SUM(npss_quote[Price 
ex. GST],10)))

I got it working with this

=SUMIF(npss_quote[Service],"<>*Activities",npss_quote[Price 
ex. GST])
