Hi Peter Herth and everyone else,
I'm rather new to Lisp and to LTK, but learning steadily. I'm stuck with
a problem. I've successfully used ltk to create a form, but don't know
how to save the data entered into the form to my database. I suspect
that my problem is improperly supplying the data from the entry widget
to the store-save-rec function (see line 279 below). But I may just have
something else fundamentally wrong.
Would someone please tell me what I'm doing wrong, and how to fix it?
I'm using ltk 0.91
Thanks in advance!
Lou
PS Also, how do I clear all the fields in preparation for entering
another record of data?
