I have a form with 5 pages. A textbox on page 4 is actually the sum of five fields on page 5 which I have coded in the Refresh Propery on page4 as follows:thisform.ws_pageframe.page4.txtProj_Mhi.value = thisform.ws_pageframe.page5.mhi_amt1 + mhi_amt2 + mhi_amt3 + mhi_amt4 + mhi_amt5 However, when I compile and run the application and click on page four(4) I instantly receive an Error Message telling me that the propery mhi_amt1 is not found. Any ideas what I am doing wrong?! Thanks Rick
