How to auto populate a field when the record in loaded

[cpinedatx94]

i need a field to auto populate when a record is loaded or when the name of the "technican" field is changed.

This field i need auto populated is a address field and the value of that field is stored on a whole other table.

i need a way to pull that value from that field and table into my new form and auto populate. 

I would like for the "address" field to populate whenever the "technican" field is changed.

How do i go about doing this?

Hi, 
You can write a onChange cliet script on the field "technican" and use GlideAjax to populate the address.
