Trying to hide field title and suffix when empty

[jodancer]

Been trying for I just cannot make it work. (pretty useless I know!)

 

Could anyone take a look and point me in the right direction?

I don't understand what you are trying to do: do you mean you have something like :

 

<td> aNameForTextfield </td> <td> <input type="text" name='aTF' value=''/>

 

and you want to hide aNameForTextfield as long as their is no entered value?

Hi,

 

Thanks for the reply.

 

I have a number of fields and these have a title a possible suffix or prefix

 

Example

 

Number of Bedrooms: 4 Double

 

In this case the

 

Number of Bedrooms is the Title of the field

 

4 is the input value

 

Double is the prefix

 

If the field is not filled in (in this case 4) then I would like Number of bedrooms and Double hidden
