Re: Adding scripts

Tim, It is not necessary to retrieve your values using $HTTP_POST_VARS, the variables can be referred to by their name, e.g $hit_955 so in PART 1 it appears that you are intialising everything that was passed from the select page to 0. All you need to do is initialise your counters. PART ONE: <? $SubTotal = 0; $FormattedSubTotal = 0; $Total = 0; $FormattedTotal = 0; $PST = 1.08; $GST = 1.07; $CalcPST = 0; $CalcGST = 0; $FormattedPST = 0; $FormattedGST = 0; ?> I would say that the 3 items that you are getting values for are spelt incorrectly in that initialisation section and are not getting zeroed. The problem is that the missing values will be a null string and your calculation will fail. For each value passed you will need to do a test and set to 0 if the variable does not exist e.g.:- if(!$hit_955) { $hit_955 = 0; } etc...
