I have a subform listing items for purchase. Some are services and are not taxable, some are products and are taxable.
So far, I am calculating the sales tax for each record (item paid for), based on whether the thing is taxable or not and putting that result in a text box (txtSales_Tax) on the form. Since these calculated amounts aren't stored in a field, I can't SUM them, since SUM only works on data in table fields. Can someone tell me how to get a total?
Otherwise, I'll get rid of txtSales_Tax entirely, if someone can tell me how to write a SUM function, as a Control Source, that includes an IIf, or a WHERE, so it only adds items where the yes/no field Taxable=True.
I've got an IIf with a SUM function in it but, even in the footer, that only works for the current record. I need a SUM that has a nested IIf or WHERE in order to include all the records.
