New to MS Access and had a question. I am trying to add the value from txtKits and txtFG. I want them to show up in a seperate textbox called txtTotal that returns the value (the textbox also needs to non editable). Here is what the form looks like:
If the user enters just one of the two calculation fields, then I get the attached output. I want it to not give that output. It can stay blank until both are entered. Any help or suggestions?

You can check if both fields are numeric first in your calculated field:
=IIF(IsNumeric([Field1].Value) AND IsNumeric([Field2].Value); [Field1].Value + [Field2].Value; Null)
