Ok tech support got a hold of me earlier and suggested I remove Eric Otts Wireframing extension and re-install forms builder which I did with mixed results.
Here's what happens;
re-installed forms builder
I open DW and create a new php page
insert form, Specify Action Page field NOT populated
F12 in IE8
"Parse error: syntax error, unexpected '"', expecting T_STRING or T_VARIABLE or T_NUM_STRING in C:\xampp\htdocs\Milica\TMP4yz72wgjdf.php on line 5"
So now I did not save the previous php after inserting form and close it without saving so form code is discarded.
open previous php
insert form, Specify Action Page field populated
Basically when creating a new php page and immediatelly inserting form, it will not populate the Specify Action Page, when I pointed this out to the support person he said it did not matter that it would default to the open page. But it must matter otherwise it should work no?
I guess I can live with the work around if it holds but it'd be nice if we found out what's wrong. Does anyone else have the same or similar problem?
