You need quotes around WeightID and StarID. Dan
-----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Madòrick Sent: 02 August 2005 00:45 To: [email protected] Subject: Re: [ASP] Updating a CHECKBOX when a value is entered in a FORM I really appreciate all of the help with this problem. I tried the code suggested, it still is not working. I'm not getting an error just not updating the checkbox. I haven't been able to find any documentation on the "document.getElementById command". Please see the attached code and tell me what might be wrong. I also thought the assignment in the "var" command might need a "==" but no luck. <SCRIPT language="JavaScript" type="text/JavaScript"> function checkWeight (WeightID, StarID) { var Weight = document.getElementById (WeightID); var Star = document.getElementById (StarID); Star.checked = True; } </SCRIPT> <FORM name="Player2" method="post" action="EditTeam.asp"> <TABLE width="80%" border="0" cellpadding="0" cellspacing="0" summary="Summary"> <TR> <TH scope="row"><LABEL> <INPUT name="FirstName" type="text" id="FirstName" size="17" maxlength="15"> <INPUT name="LastName" type="text" id="LastName" size="27" maxlength="25"> <INPUT name="MI" type="text" size="3" maxlength="1"> <INPUT name="BirthDate" type="text" id="BirthDate" size="12" maxlength="10"> <INPUT name="JerseyNumber" type="text" id="JerseyNumber" size="4" maxlength="2"> <INPUT name="Weight" type="text" id="Weight2" size="5" maxlength="3" onChange='checkWeight ("Weight2", "Star2")'> <INPUT type="checkbox" name="BirthCert" value="True"> <INPUT type="checkbox" name="Star" id="Star2" value="True"> </LABEL></TH> </TR> </TABLE> </FORM> Any and all help with this is greatly appreciated.
