Adding scripts to NewForm.aspx

Hi!

Yesterday i was adding a new script file into a NewForm.aspx file.

I had a problem with this because when i added the <script> tag with the file reference src=”” it doesn’t works.

I found that i have to put that in a content but i want to do it adding the tag in the NewForm.aspx. Can i do it?

I don’t want do it writting the JavaScript code into NewForm.aspx, want to add the Scrpt REFERENCE.

Can you tell me about this?
