Hi everyone, this is my first post to this forum. I have inherited an Access Database and need to add a field on the form that will take the result of an arithmetical calculation of 4 other fields, compare the result with another 2-column table and display the resulting figure in a new field on the form. I can do the calculation and get that to appear in the new field, but can't get the final look-up and display. All suggestions gratefully recieved.

Mike
