alright i have a invoice form that uses a subform to select products. it
looks up the ID for each product and is bound to a table called suborders. it
also looks up its in stock value and then subtracts the quantity field from
it and then is bound to a field called in stock also in the suborders table.
i need to know how to take the new instock from the suborders and
update/append it to the table where all the inventory is stored. it should
overwrite the old "in stock" with the new one. how do i do this, i know it
has something to do with the criteria and i tryed putting the criteria as the
products ID but it doesnt work so maybe im entering it wrong but will someone
please help me.
