Using SDT 5.1h

I had renamed a field in a table structure and had changed the field type from DATE to DATETIME. The field is located in the middle of the table structure. When i go to update a particular client's database, i get the following error:

Error #12, Line 423 of UPDATEONETABLE
Code Variable TAKENDT is not found

That line of code looks like:

alter table (lcAlias) &lcToDo

The table being updated DOES have the field TAKENDT in it

The particular field in question has in its SDTMETA record the following:

PREVNAME: RTAKEN
REALNAME: TAKENDT

Any ideas?
