I have this formula that will draw a certain number out of a table
=IFERROR(VLOOKUP($C$4,$C$20:$L$46,7,False);"")

Now what i would also like my formula to do is be multiplied by 1.5 IF the value in basis!D19= bigger than 2002, other wise the value may remain the same
And if possible i would love it to be round up to a number 5/10/15 etc

I am just here wondering wether this is even possible, so if not please inform me. Any suggestions would be greatly appreciated since this is way beyond my skillset, thanks!
