Thank you so much for taking the time to resoond! I really apprecaite it. However, In Lifestle Deesigner 8, whered do I enter this script? If I right cick on the check box, and then choose the object palette, the only possible place I see to place the script is under the values tab, where there are spots for an empty message and for a validation script message. This is very confusing as there is also a check box for "error" in the validation script message area, and this seems to logically imply that if I put the script there, the script will only execeute if there is an error.
