Show this field if - Problem

[Tom.]

Hello,

I currently have a block system which you can select between large and small blocks. Between this there is an excerpt field that will only allow a string of a certain length. 

So I have a excerpt field (max length 100) and a excerpt_long (max length 200) field. To choose a large and small block is an option field and the only editable for the SuperUser as I don't want Moderators deciding on the sizes of the blocks. 

What excerpt field displays is based on that option field. It all works well, you set it to large, the max length is 200, if it's small it's 100. However, if you are logged in as a moderator where you don't have the option of setting the block size you also don't see the excerpt field.

I've tried ticking this field is visible but not editable for those who can view it. However that doesn't work.

Anyone got any ideas?

Thanks,

Tom

Any ideas on how to get around this?

Inputfield dependencies work by looking at the input values in the html. If a field is not editable there's no inputfield rendered and therefore no value to be found.
