Wierd problem

[sunshine3]

Hi all,

I have this wierd problem with one record.I have a student table and team and degree table related to it.So in the student layout i created a portal that displays the degree and team of each student record.On the layout screen , i have a student number ,unique to each student.Beside this field i created a button that search a student record based on first name or last name or student number.

What i did...

I Could see a record for one student eg. student number :123456,in the student number field.Now , i tried experimenting by typing a different student number in this field(in other words overriding the value in this field and then clicking on search button.

This gave me an error and now when i see the record for this specific student i can see "?" in the student number field.I tried typing the correct student number and also deleted this record and recreated it, but still, the "?" question mark does not go.

What did i do wrong here???

By the way, i had set the student number field to "Allow over ride during data entry"

Help will be appreciated!

Thanks,
