Using formulae in edit table

Hii  there,

I am new to analytica and trying to using formulae in edit table, but after changing the index the formulae doesnot reflect the changes made in the index nomenclature.

Even if i try to make formulae in excel and try pasting it in the edit table it comes as a text and i need to remove the doubles quotes around it (even tried psting it as unicode text but still the problem with the quotes remains), can i get help around this.

Thanks.
