I have a form. On the form are multiple fields that the name only varies by a number (txt_issues1, txt_issues2, etc.) My form has a button that opens up a new window. I can select data in the new window, and want it to pass back to the original form into a specific one of my text fields. The only info I have about which text field is the number. I tried this code:<BR><BR>//This field hides the corresponding number for the field<BR>tmphidden = document.frmISSUES.text1.value;<BR><BR>//tried to concatenate the 2 fields to give me the field from the original form<BR>tmpvalue = "txt_Issue" + tmphidden<BR><BR>//then tried this to move it over<BR>window.opener.document.frmTmSht.tmpvalue.v alue = document.frmISSUES.Cbo_Issue.value;<BR><BR><BR><BR >If I hard code a specific field in it works, but I don't have the specific field just the number. How can I use that number to tell which specific field to pass back to?
