I have this code (below) that won’t work. I am trying to use it on the OnChange event of a one field, so that it changes the date of ANOTHER field (LastUpdatedField). Any ideas.
Thanks!!
Luis
function ChangeDate(LastUpdatedField) {
document.forms[0].LastUpdatedField.value=Date()
}

As long as you are calling that function with the fieldname in question being passed in as a string, then it should work.
eq:
ChangeDate(“LastUpdated”);

document.forms[0].LastUpdatedField.value = document.forms[0].TheFieldThatJustChanged.value;

Solution (Thanks to all):
Steve was correct. This worked for me:
function LastUpdate(fld){
var fldName = eval(‘document.forms[0].’ + fld);
fldName.value = Date();
}
And you call it using:
LastUpdate(“FieldName”);
This function is handy for changing a field to hold the date that another field was changed.

¡Hola! 
You may want to use the “eval” function. Something like:
function ChangeDate(fld){
var fldName = eval(‘document.forms[0]’ + fld);
fldName.value = Date();
};
(I didn’t test it)
What type of field are you trying to call this from? Is it an editable field or a listbox? Have you tried it in the “onBlur” event (i.e. when exiting)? Try it in different events after using the “eval” function.
Good luck!
