Hi,
I have a Foreign currency bill making sheet. In that I would like to sort the following problem
----- I----------------- J -------- ------ K ----------------------- L ----------------- M
PURCHASE/SALE------- FCY----------QUANTITY------------------RATE-------------LOCALY CRRNCY
in the fourth colomn(L-RATE)) there is vlookup formula that brought the currency rate from the RATE sheet. The formula is
=IF(ISNA((VLOOKUP(J2,RATE!$A$1:C$32,IF(I2="P",2,3),FALSE))),"",VLOOKUP(J2,RATE!$A$1:C$32,IF(I2="P",2,3),FALSE))

Now i wanted to give the rate colomn some control limit by giving either if formula or some conditional formula . ie. If 'I' colomn is P(purchase),'J'colomn is USD, the 'L' colomn gets by vlook formula(above mentioned) as the rate 386. Now i can change the rate to any value, even zero also possible.

Here is, my question: how can i prevent that 'L' colomn between 384 and 386 (any rate between that is ok) but cell should not accept less than 384 or more than 386.

I know this is bit complicated issue. Still I know there are masters in this group they can make impossibles(what i think) to possible.

Any suggestions or ideas are heartly welcome.
thanks and regards
