Hi
Please could someone help to create a formula linking Hrs Left on Contract under Contracts to the Hours Worked under Service Timecards.
I would like to subtract the total number of hours worked on all timecards relating to a single contract and create a field on the related contract to show how many hours are remaining. At the moment the link to Hrs Left on Contract leads to an error page.
The formula for the Hrs Left on this Contract button is currently: ={!Contract.Total_Hours_of_Service__c} - {!SFDC_Service_Timecard__c.Hours_Worked__c}
Does anyone know how to fix the error and the formula?
Cheers
