Macro run time error 6

[macdca]

I have a macro, that has been working fine for months until last week when I have started getting a runtime error. My code is below, and the error is highlighted in red? can anyone help??

What is the 'spec' of the macro?

What is it supposed to do?

Perhaps it's just me but it's not clear from your before/after or the code itself.

 

[macdca]

It seems to be working by removung the Int - thanks

It's not only you Norie
