Thank you.

Another solution is to change documentstyle to documentclass

Hi Stephan,

I have uploaded the file with this post.

There actually are no packages used in the file as I am building my final documents in sections. So currently it is a plain tex file.

Thanks for your help so far.

I hear you that it is working for you but it is not working for me at all.
Could there be another reason why mine is not working?

I'm using MikTex 2.9.

And these are not working:-
Along with a few more very similar

I'm trying to get curly letters using \mathcal
e.g. \mathcal{F}
this works perfectly well but If I am trying to add a subscript to F, i am getting a > as the subscript.

I've tried both \mathcal{F}_i and \mathcal{f_i}

Any help would be most welcomed, thank you
