A table contains a field containing an abbreviation with the abbreviations and descriptions kept in a seperate abbreviations table how would one use the LOOKUP() to display the description rather than the abbreviation?

I've tried the following code in the textbox refresh event, but there seems to be a delay as I scroll thru the records.

LOCAL lcAbbrev
lcAbbrev = TRIM(THIS.value)
IF !USED("abbrev")
USE abbrev IN 0
ENDIF
SELECT abbrev
lcAbbrev = LOOKUP(descript, 'COLOR ' + lcAbbrev, abbrev, 'TYPE')
IF !EMPTY(lcAbbrev)
THIS.value = lcAbbrev
ENDIF
