Calculating Sales Tax

[Derek]

I am trying to create a purchase order in InfoPath to be placed on a
SharePoint server. I can get the cost of items to SUM, but I can't get the
sub-total to multiply by a percentage to calculate the Sales Tax.

Any help would be appreciated.

Hey Derek.

Are you saving the sum result in a field?

You should be able to do it even with out that by either Sum(field) *
taxamount
Or add another field to the item records for computing item cost + tax and
then sum that.

Give me more details of what you want if that does not help.
