when you set focus, your script is only using the field ID such as

myTextBox_0.focus();

The field id is just a string so you're essentially doing

"my string".focus();

the focus() function is an object method so you need to use it against an object, in this case, a pointer to the textbox.

I'm assuming that the abc function is passed a field reference, if so, then just do

field.focus(); //(not fieldname.focus())

ok right off the bat the submit button is trying to run a validate() function that doesn't exist in your pasted code. Was this function renamed or removed?
