plz help

What the exact problem?

if you add print statements in def validate, they will show on your bench console.

the problem is i edited both the files…but there is not done any kind effect to my form… if i add attendee in my form it will not fetch the name of user as i want …i refred all vedio as it is which is given in frappe tutorial…but datz not work for me…

this is my form;

You have to try and debug using the browser JS console and the terminal and find where exactly your code is failing.

i tried …there is no error found in my code…what i do…

Try,
var attendee = locals[cdt][cdn]; in place of var attendee=frappe.model.get_dco(cdt,cdn);
this should work, also its frappe.model.get_doc(cdt,cdn);

There is a syntax error. You have misspelled doc.
It’s “frappe.model.get_doc”.

now i got this error in browser console…
Failed to load resource: the server responded with a status of 404 (NOT FOUND)
