Browse lookup field not found error

[Richard Kreiss]

Windows

Filepro 5.7.03.07

I have the following code for a browse lookup which when executed displays the field not found error at an @bk when the option has not been selected.

The problem is at line 196 & 197 which executes the browse.  If I use the browse created by the wizard, no error occurs (line 196).  If I use the browse command at 197, it appears that the @bk = "c' line executes and the field not found error occurs.

If I use the debugger, the browse appears and line 200 shows as false as @bk is empty.

If it is empty as line 200, why is line 201 executing as @bk is empty.

More to the point, as I indicated, the programming works correctly when run from a wizard created browse?

Anyone see why I am having this problem as other browses written similarly work properly.
