If both values are numeric Charlie's code would save the sum to text9's text property.  If one text property (or both) returned a string Charlie's code would concatenate the two values. If the contents of a text property is not a codeblock using the () CALL operator should generate an "Expression expected" error. Charlie is not reporting an error or a concatenation.  He reports that on occasion text9.text is blank.  The most likely cause for the blank text is a NULL value tucked in there somewhere.  Adding NULL to anything results in NULL. The text6 object doesn't have a value property.  If it's text property contains a codeblock val(this.parent.text6.TEXT) would return an "Expecting character" error. Mervyn.
