New Post: How to write in an existing xls file ?

Hi Mark,

My spreadsheet is not too big, it has some formulas, but is a small file with only two sheets and about 50 rows and 30 cols each one, but I am not sure if it processing all cols and rows (65535) in the sheets. I just noticed it has 2 small images, could they be the problem?
I am also loosing 2 formulas from the document when saving again after modifying the file, it seems to that is because they have a VLOOKUP formula.

=IF(B22="","",IF(ISERROR(VLOOKUP(B22,Precios!$A$3:$C$470,2,FALSE)),"Producto no procesado",VLOOKUP(B22,Precios!$A$3:$C$470,2,FALSE)))

And the code I pasted is all I have.

Any idea?

Thanks!
