if statement for +/- a percentage

[marshy3300]

Hello, I'm trying to display a tick or cross in F if a variance (D-C) is less than or greater than C but i'm having a total mind blank. Should be easy but its not!
I've got the wingdings side easily just the formula is stuffing me around

So

Num1 ...Num2 ...Variance.....Mark
C.............D............E...........F
600 ......600............0........Tick
13 ........14 ............1........Cross
312 ......308 ..........-4 ........Tick
312 ......388 ..........86 .......Cross
312 ......333...........21.........Tick

if a variance (D-C) is less than or greater than C

If that's the case....why is one of these a tick and the other a cross ???

312 388 86 Cross
312 333 21 Tick

86 (though my math sucks and should be 76) is greater than 10% of 312 so its a cross
21 is within the +/- 10% mark

Really bad day..... This is all based off +/- 10% variance from C

So this

=IF(ABS(E1)< ABS(C1*0.1),CHAR(252),CHAR(251))

Thanks Michael,

Looks like that only works if the variance is 0. Otherwise all the examples show wrong though the symbol does change over the course of the sheet

Amended - Wrong cell references... Works a treat
Thanks heaps
