texte = Brian and Kenneth,Thanks for the pointers. The Shipcost modification appears to work. Can you explain the [hideif 0=[math]0[lineitems] syntax, something I've seen in several places. I assume the whole calculation is hidden if the result is 0 ([hideif 0=0]) but what does 0[lineitems] do? Is this interpreted as 01 for the first lineitem, 02 for the second, etc.?I'm still have problems with the sales tax. Maybe I don't understand the point of [interpret]. In the example I posted below, am I supposed to put [interpret][taxRate][/interpret] in my .tpl file? This doesn't seem to work; the tax always comes back as 0.00. However, if I embed the [lookup] directly in my .tpl page, it returns the proper percentage.Thanks for your valuable advice,Kevin Lippert On 12/14/99 2:06 AM, you wrote:>For the tax problem, make sure you have a field in the database named >taxable with each product set to true or the tax will not work. >As for your shipping, you need to fix your formula a bit. >You formula: >Shiptype [math]2.00+([lineitems](1*[quantity])[/lineitems])[/math] >should be called shipcost, and is not going to calculate correctly because >you need to make it show everyline item qualtity. >Try: >Shipcost [hideif >0=[math]0[lineitems]+[quantity][/lineitems][/math]][math]2.00+(2.00*(0[linei >tems]+[quantity][/lineitems]))[/math][/hideif] >This will add all the quantities up for you and also zero out the shipping >cost if they check out the shoppingcart page before any items have been >added. > >Brian Boegershausen >WebCatalog Programmer >www.orderbywire.com >----- Original Message ----- >From: Kevin Lippert
