V4RB Need help with Retrieving Method Results

[Mike Albert]

Thanks Ruslan,

Do I need to define the in the RB code the formula's for that method?  I already did this in VAPP and they're working fine from AppleScript and within VAPP.

These DB's were previously created in VAPP and have been used for many months with AppleScript.
I am unable to get any values from the method fields.

I just looked through the Test example and tried the following :

vCategory = vConfigRecordsCursor.StringField("category").value

I still get the exception error on this.  I am guessing I am doing something really wrong....I just can't figure out what!

Regards
Mike
