Getting blank space in Adobe form out put

Hi Experts,

I am using floating fields to display data dynamically in adobe form.

Example:

{var1}

{var2}

{var3}

{var4}

but dynamically {var2} value is coming blank as value is not getting fetch from back end.

and layout also getting change like,

{var1}

{var3}

{var4}

Now client want instead of this blank value can we push up {var3} to below {var1} like,

{var1}

{var3}

{var4}

please suggest your answer if it is feasible.

Regards,
