Email Address field misaligned?

[webbouk]

On our store using the 'Split Screen' feature which I beleive is part of: http://www.zen-cart.com/wiki/index.p...ithout_Account

when a customer goes to the checkout page 'Step 1 of 5 - Billing Information' the email form field in the 'Returning Customers' table is above the text: 'Email Address:'

I've attached a screen shot to show you what I mean.

Where do I find the code to correct this and place the email address form field beneath the text 'Email Address:' ?

Thanks
