Divide by zero error encountered

Working on an Access ADP with SQL backend.  I've got this one Function that keeps giving me this error. "Divide by zero error encountered".  This is the statement it gives me this error at:

CASE WHEN [todayconcpoured] > 0 THEN ((([todayconcpoured] / [todaytightconc]) - 1) * 100) ELSE 0 END

Both fields have 0's instead of nulls.  
I have been researching this on EE and I have tried with no success :

CASE WHEN [todayconcpoured] > 0 THEN ((([todayconcpoured] / CASE WHEN [todaytightconc] IS NULL THEN 0 ELSE [todaytightconc] END) - 1) * 100) ELSE 0 END

Can someone help me with this please?
Thanks

this should work better:
CASE
  WHEN [todayconcpoured] IS NULL OR [todaytightconc] IS NULL THEN 0
  WHEN [todaytightconc] > 0 THEN ((([todayconcpoured] / [todaytightconc]) - 1) * 100)
  ELSE 0 END
