-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all. Thanks to those who have volunteered to help with this. Here are the relevant code bits: First the button: <input type="button" onclick="SetCheckBoxRange('mainform', 'request');" value="Select range"> and then the function: <script type="text/javascript"> <!-- function SetCheckBoxRange(FormName, FieldName) { if(!document.forms[FormName]) return; var objCheckBoxes = document.forms[FormName].elements[FieldName]; if(!objCheckBoxes) return; var countCheckBoxes = objCheckBoxes.length; if(!countCheckBoxes) return; confirm('We're running the function!'); // this line is for debugging. // I wanted to see if it was even running the function up to that point. // It didn't pop up, so I don't think it was. var CheckValue=false; for(var i = 0; i < countCheckBoxes; i++) { if(objCheckBoxes[i].checked && CheckValue == false) CheckValue=true; if(!objCheckBoxes[i].checked && CheckValue == true) return; objCheckBoxes[i].checked=CheckValue; } return; } // --> </script> As mentioned before, the function will go through the form until it finds a check box that is checked. When it finds one, it will continue to the next checkbox and if it is not checked, it will check it. It continues doing this until it either reaches the end of the form, or until it encounters another checked checkbox. When it finds either, it will exit the function. That's at least what it's supposed to do.
