I have a field name in my water line data named " Diameter" the field is set as a text field string. I am trying to do a field calculation to add 6" diameter. I have tried several variations; "6" "" , "6" &"" "6 +"" . I am using the parser vb script. None of these codes work. I have no problem when I enter in "6" in the field calculation to add the number 6 to set as the diameter. The problem is able to add in the inches symbol ". Should i use the parser python instead of vb script? if so do i select the field as a number or string?
