How to utilize the space of the hidden fields ?

Hello,

I’ve designed an adobe form using the transaction code SFP in SAP.

In that form, I have 4 numeric fields. If the value of any field = 0, it will not be displayed at run time, and that is done successfully. But a space is displayed in the place of that hidden field like this:

Field1: 11111

Space

Field3: 33333

Field4: 44444

I want to utilize that space to be occupied by next field like this:

Field1: 11111

Field3: 33333

Field4: 44444

I’ve already searched about this matter in this site, but I did not get a complete answer.

Plz help me step by step what to do to eliminate that space.

Regards......
