title: ms access: #Name? Error
body: <p>In my form I have a text field. Control source for the field is <code>=[MyTable1.MyVal1]*[MyVal2]/100</code>. This was showing value perfectly so far. But from yesterday it is showing this error <code>#Name?</code> in the field. I don't understand what suddenly went wrong. Please help me with how to make this working. </p>
