rbuchanan getting error about Arithmetic expressions must use numeric arguments
Hi. I'm attempting to write my first APEX code in the form of a trigger. I have a custom field on the Opportunity Product page called "Refurbished__c". It's a checkbox. If the salesperson checks that box on the item he's adding to the opportunity, I want the list price to automatically get a 65% discount and show that calculated amount on the same page that he checked the box.
My code so far is this, but I get an error on line 3 just after the "=" sign when I try to compile (error message in subject line above) Any help would be much appreciated! Thanks.
trigger Refurbished_Checked on OpportunityLineItem (After Update) {
if (OpportunityLineItem.Refurbished__c) {
OpportunityLineItem.ListPrice = OpportunityLineItem.ListPrice * 0.35 ;
} else {
OpportunityLineItem.ListPrice = OpportunityLineItem.ListPrice ;
}
}
OpportunityLineItem is not a valid object. You need to iterate through the Trigger.new array. I also recommend changing to a "before update" trigger so you can more efficiently change the ListPrice field value. Lastly, I commented out the else part of the if/else statement since it didn't do anything to the ListPrice value.
Here is a revised version to show you what I am referring to:
trigger Refurbished_Checked on OpportunityLineItem (Before Update) { for(OpportunityLineItem oli: Trigger.new){ if (oli.Refurbished__c==true) { oli.ListPrice = oli.ListPrice * 0.35 ; } //else { // oli.ListPrice = OpportunityLineItem.ListPrice ; } }
