What about Helmets?

Using the 3.5 Dungeons & Dragons Character sheet from ROll 20.  Is there a place in the Armour section where I can add the information for helmets or do I simply combine that with where I have put Mail Shirt?

First, there is no 3.5 D&D sheet by Roll20, but based on the screenshot it looks like you are using the D&D 3.5E sheet by Diana P.  Second, 3.5 doesn't usually have an effect for wearing helmets, so it isn't going to be in most sheets armor section.  If you are using a house rule where helmets do something atypical my suggestion would be to create a note of it somewhere, or depending on the sheet make it a modifier to an existing item like your armor. 

I was thinking of just combining the helmet and it's modifiers with where I put in Mail Shirt and making a note of that. It's a pity you just can't open another tab for it.  Thanks for your advice.

Perhaps put it in the Other Armor bonus section. 

I would look everywhere on the sheet for that, but you could show me with a picture please...

I have included another screenshot to show you...

I was suggesting you click on it in case you had it closed, yes open it and add the entry where desired. I don't know the effect of your Helmet since it is a house rule so you will have to add it where appropriate.
