Hello,
I am trying to use Field Calculator to collect values from multiple fields in a feature class. I only want records with no value to be filled in with the Field Calculator result. Since I am setting this up for automatic updates, I am trying to program this within Model Builder. However, my relative lack of programming experience is holding me back. Right now, my attept to program this goes as follows:
(Using Python as the Parse)
Pre-Logic Script Code:
If !STR_ADD! = " " Then
STR_ADD=
!STR_NUM! +" " + !STR_PRE_DIR! +" " + !STR_PRE_TYPE! +" " + !STR_NAM!
Essentially, if my STR_ADD field is empty, I want to fill it with the combined values of the other four fields mentioned. I want to continue with the code to add values from other fields when some of my records remain empty. However, if I can't get this first part completed, it is hard to continue.
Thank you for your help in advance!
Colter
