Calculate Field in Model Builder

DavidJud — Thu, 05 Aug 2010 13:53:38 GMT

I want to calculate a new field using the model builder.
The new content is the "sum" of a text ("U") and a number field.
I use the VB-Expression "U"&Left([GST_def],1).

This expression works fine if I use it in the Attribute Table -> Calculate Field but it does not work within my model.

I attached a .jpg with my Calculate Field funtion.

Thanks for you help.

Hello David,

can you please attach the toolbox holding the model and possibly any data needed?
Can you clarify this "...use it in the Attribute Table -> Calculate Field " - I do not know what you're referring to here.

Thank you, Barbara Bicking
