Recordset FindFirst Not Working, Why?

P: n/a
Hello:

I am an ambitious novice...I have a main form "frmGeneralContracting"
that has a subform on it called "frmsubDeliverables" and I am trying
to restrict editing if the current user's login name is in another
subform "frmUserNameRightsProject2Names" that is also attached to the
main form. I want to allow edits, deletes, and additions on the
frmsubDeliverables form to the record and if not they only can view
that record.

I call my GetUserNameRowSecurity function on the OnCurrent event of
the subform frmsubDeliverables.

I have looked at this all day and I can't figure out why my recordset
findfirst isn't working. It seems to totally disregard my code...if I
set the subform properties on the form to false for all 3 allows I
can't edit any records even if my username is in the
tblUserNameRightsProject2Names and if I set the subform properties to
true I can edit all the records regardless if my name is is in
tblUserNameRightsProject2Names for that particular record.

My module code is below. Any help is greatly appreciated. PLEASE
help me.

I believe that this...

rst.FindFirst ("[tblUserNameRightsProject2Names].
[fldUserNameProjectEdit]" = "'" & stUser & "'")

Should likely look like this...

rst.FindFirst ("[tblUserNameRightsProject2Names].
[fldUserNameProjectEdit] = '" & stUser & "'")

Your useage of double and single quotes does not build a valid
statement.

Thanks storrboy my quotes were messing it up but now I have another
problem that I think is related to findfirst and the recordset query.
I want the code to allow the user to edit, add, delete only if the ID
field in the subtables match AND the login names match. Instead it is
allowing editing, adding, and deleting for all project IDs just as
long as the users login name is somewher in the subtable
"tblUserNameRightsProject2Names".

Can you figure out why? How can I fix it? I'm stumped...my revised
code is below. Thanks in advance

Try this. I've added and removed (I hope not too much) as somethings
were redundant, some were not used and some were hard to follow.
Compile the module before running to catch syntax or spelling errors.
If it seems to work at first, try it a few more times to make sure.
