#NAME? error on if statement

Hi Guys, i am using the following formula in cell F5:F7

=IF(E7>0,CONCATENATE(FIXED(E7*100,2,TRUE),"%",REPT(“”,10-LEN(FIXED(E7*100,2,TRUE))),”▲”),IF(E7<0, CONCATENATE(FIXED(E7*100.2,TRUE),"%",REPT("",10-LEN(FIXED(E7*100,2,TRUE)))," ▼"),CONCATENATE(FIXED(E7*100,2,TRUE),"%",REPT(" ",9-LEN(FIXED(E7*100,2, TRUE))),"◄►")))

It works in F7 but not F5 or F6 and is resulting in #name? error... and im not sure why this could be! any suggestions would be appreciated!

I have attached the workbook if that helps.

Many thanks
