Too long database function shortened

[sle7en7]

I had a nested IF function on one of my database cells. It runs fine but after I got out of the worksheet and tried to edit again all there was displaying was this part;

=IF(CONCAT, 12, IF(' (', AREA(')'), AREA))

I had something like this before;

=IF(('myrecord'.'myfield'='abc'), AREA/2, IF(('myrecord'.'myfield'='xyz'), concat(12,' (', AREA,')'), AREA))

Also, the database criteria is set to; ((R IN ['myrecord'])) if that helps anything.

Anybody have an idea why this is happening or is it suppose to happen?

All help is much appreciated.
