It should be possible to pass an ADODB.Field object to the function. To test that this will work, try adding a:
Dim myField As New ADODB.Field

under the Dim MyRS.... Then add a:
Set myField = MyRS("PolicyNo")
or
Set myField = MyRS!PolicyNo

then pass this value to your function (WF()). Also, since MyString should be a string or variant (note return value of function WF()) you should not use the Set command. Instead try the following:
MyString = WF(myField)

This may help narrow down your problem. Also by specifying the .Value property of the field when looking at the value may help follow the code and make it compatible with the new VB.Net which eliminates default properties.

Hope this helps.
