hi ,

i try but still,

How long is your Nam field? 50 characters.
Add spaces at the end of "PRIVATE" to be the same length as your NAM field.
you mean "PRIVATE"+43characters.

this.ReadOnly = ALLTRIM(EVAL(thisform.Grid1.RecordSource+".Nam")) == 'PRIVATE                                          '

i try ,mr.Borislav Borissov code, still

this.ReadOnly = ALLTRIM(EVAL(thisform.Grid1.RecordSource+".Nam")) == 'PRIVATE'

thanks.
