Hello:<BR><BR>I&#039;m trying to do the following: 1) a radio button with multiple choices, c4, value=1 is checked. 2) value in C6 can&#039;t be blank. 3) the value in c6 must be numeric. Someone shared the code to validate that the box is not empty and value is numeric, but I need help tying in the radio button.<BR><BR>Here&#039;s the code:<BR><BR>function DataValidation()<BR>{<BR><BR>// this is the piece I need to combine with the code starting with var.<BR><BR>if((document.report_incident1.c4[0].checked)<BR> <BR>//<BR>var val=document.report_incident1.c6.value; <BR> (val.length==0)<BR> {<BR> alert("Please enter number of reports.");<BR> return false;<BR> }<BR> var digit="0123456789";<BR> for ( var c6=0; c6 &#060; val.length; c6++)<BR> {<BR> if(digit.indexOf(val.charAt(c6)==-1)<BR> <BR> {<BR> alert("Please enter a number for the amount of reports.");<BR> return false;<BR> }<BR><BR>Thank you.
