Is there a way to replace Null Value in Model Builder?

[JessicaRutherford2]

Hi 

I am looking for a way to replace Null Values (-9999) with a set value in Model Builder. I have extracted values to points and want to replace the Null values with a set value. I have tried an iterator but that doesn't seem to work. With raster image I used Is Null and Con Null tool to replace the value. I am not to sure if this is possible for extract values from points. When I do this manually I go through edit mode and do a find and replace. But this is not work for Model Builder. 

I was wondering if there is a script I could use or a way around this issue. 

I need to replace the -9999 values with -13.54.

If anyone has any ideas, that would be great.

Thank 

Jess

Hi Dan

I understand...I think...what you are saying. However, I feel like this is what I did. I tried again this morning but i still only gives me the replace section. I can not see in the Selection by Attribute any way to replace the null values and retain all other values. Am I missing something??? Even when I specify the full extent to include the polygon area, it still is only giving me the section with replaced null values.

Please see my steps below. Can you see where I might be missing something.
