Excel security

I have sent a spreadsheet by e-mail to a mate but he can't open it properly. He has set macros to low etc but it says 'request the macros be signed by the author using a certificate issued by a Certificate Authority'!

What does this mean? And what do I do please?

I assume that the spreadsheet actually does contain macros?

This message should not appear if he has macro security set to low.

Indeed it does contain macros and he has set it to low although the error still appears. I have a screenshot of the error should you need it.

A screenshot would help plus the versions of Excel that you both have.

My e-mail server is not allowing me to e-mail at the moment so I can't send screenshot VoG. I will keep trying.

you could upload to somewhere like:

if email is a problem.

Sounds like this:

click here

But alas the solution is what Vog suggested.

May have to re-start excel/re-open sheet for it to take effect after changing security to low?

click here I hope I did this right!!!

I looked at that link just now silverous. I am informed that he set to low, shut-down and re-opened then this error occured.

Blimey that was quick !

I think he's changing the wrong security level - that seems to be confirming that he still has it set high. Is he changing outlook / IE instead?

In Excel 2003 Tools > Macro > Security and click low (that's for him).
