Problem Updating mySQL Record

While not very pretty yet, I am trying to cobble together an update handler
for updating a "Payment" record.
It keeps trying to put NULL into "LeasePaymentDollars" field in my DB. This
is weird because I check the SQL query its trying to execute and everything
is as it should be.
I have a sneaking suspicion that it has something to do with the
tLeasePaymentDollars variables Data type.
Here is the query that the handler is producing. Note: I first tried putting
single quotes around the value and it did not work, so I tried it without
and get the same result.
UPDATE tleasepayments SET LeasePaymentDollars=1337.0000 AND
CropSharePercent='N/A' AND Notes='None' WHERE LeaseID='1075'
Here is the handler itself.
on UpdatePayment pTable, pSetQuery, pConditional
-- check the global connection ID to make sure we have a database
if sDatabaseID is not a number then
answer error "Please connect to the database first."
exit to top
-- edit these variables to match your database & table
-- this assumes a table called Table1 with 3 fields
put the text of field "fLeasePaymentDollars" into tLeasePaymentDollars
put the text of field "fCropSharePercent" into tCropSharePercent
if tCropSharePercent is empty then put "N/A" into tCropSharePercent
put the text of field "fNotes" into tNotes
if tNotes is empty then put "None" into tNotes
put "tleasepayments" into pTable
put "LeasePaymentDollars=" & tLeasePaymentDollars && "AND" &&
"CropSharePercent='" & tCropSharePercent & "'" && "AND" && "Notes='" &
tNotes & "'" into pSetQuery
put "WHERE LeaseID='" & thePaymentID & "'" into pConditions
put "UPDATE" && pTable && "SET" && pSetQuery && pConditions into tSQL
-- construct the SQL - the :1, :2 & :3 placeholders in the SQL will be
filled by variables in the revExecuteSQL line
#UPDATE Table1 SET birthDate='12/06/1970' WHERE firstName='Mary' AND
#put "UPDATE " & tTableName & " (" & tFields & ") VALUES (:1, :2, :3)"
put tSQL into field "test"
-- send the SQL to the database, filling in the placeholders with data
#revExecuteSQL sDatabaseID, tSQL
-- check the result and display the data or an error message
if the result is a number then
answer info "Record Updated."
answer error "There was a problem adding the record to the
database:" & cr & the result
