I am fairly new to Access and have no formal training on this program, just a lot of trial and error. I have a database with 4 tables. They are tblEmployees, tblCourses, tblDates, and tblTraining. The key for each was an autonumber that is EMPLOYEEID, COURSEID, DATEID, and TRAININGID. tblEmployee lists pertinent information regarding an employee (name, serial #, shift, etc). tblCourse lists all courses that are available for an employee (course name, #hours, required attendees, type of training, etc). tblDates lists all available class dates and times for the courses in tblCourses and has a lookup field for COURSEID and COURSETITLE from tblCourses. tblTraining lists all the training scheduled for and completed by an employee and has a lookup/relationship with tblEmployees for EMPLOYEEID and EMPLOYEENAME. It also has a lookup/relationship field with tblCourses for COURSEID and COURSETITLE. Finally, it has a lookup/relationship with tblDates with lookup field/relationship with DATEID and CLASSDATE. I have successfully created a form where the training can be added to an employee (frmTrainingUpdated) and it has a subform (frmTraining) with all classes for that employee in a multilist at the bottom (from a query of tblTraining). The subform also has a field for whether the training was completed and then the hours are credited to the employee (txtCredit). The problem comes when I try to add all of the credited hours for a single employee in a separate field. I am trying to create a field somewhere on the form that will total all of the hours for all of the completed classes for the one employee on the form. I have tried to list the data for the textbox as =DSUM([txtCredit], tblTraining, WHERE (EMPLOYEE=Me.Employee)) and only get an error message displayed in the textbox. I tried to do a totals SUM on the query and it only gives me the individual hours for each class on the same line for that record. Any suggestions?
