One of the reason would be that by mistake u had restricted the field not to be modified after data entry.
For this, you simply go through file->manage->database, and double click cursor for that field, in auto entry tab, clear the chcek box for
"prohibit modification during data entry"(at bottom), and come out. Now it'll work.
Hi Raj Kumar:
This field is unchecked the "prohibit modification during data entry"!
If this is a field of type "calculation" you will not be permitted to change the value and get this message. If this is a field of type text and you use your expression in the Auto-enter | Calculation field option, it will enter a default value but allow you to edit the contents of the field.
I have changed this field type to"text" and use an expression in the Auto-enter | Calculation field option.
No luck, it did not shown default value, but allow to edit drop-down list.
What is wrong?
Let ( c_ink=LINES_spot::spot_cr ; GetValue ( ValueListItems ( Get ( FileName ) ; "status_ink" ); 1 ))
In your calculation, this term has no effect on the final value: c_ink=LINES_spot::spot_cr. What is its intended purpose?
If all you want entered is the first value in the value list "status_ink", no let function is needed. Just use:
GetValue ( ValueListItems ( Get ( FileName ) ; "status_ink" ); 1 )
Since you aren't getting a value entered, I'd check to make sure that status_ink is the actual name of your value list. (If it's misspelled, you get zero values and this matches what you report happening here.)
Thank you so much :)
