Samrtforms-Wrap up test

In my one of the smartforms , in my sub-header I have aan item called Customer Acc Field : and has space on its right fro its text to apperar, just below that in the same sub header I have contract # item and some space to fill teh contract number.

Now the problem is that when the customer acct field take s some extra space in the text area and if it goes to the second line my Contact # dissaperas, which is just below it. The customer accounting Ref field comes from the the header text:

&IS_BIL_INVOICE-HD_GEN-BIL_NUMBER&

VBBK

Z010

EN.

Can anyone please tell me how do I increase the wrap up text space fopr the customer accounting ref no: field so that teh entire text appears and teh contract # which is below it dosent vanish.

Thanks
