Hiding output that has no value in emails - pseudocode

In your emails that are sent to users and admins there is often a list of values that the form has generated.

You can hide the 'empty' values using psuedocode in the email output.

example:

Say you want to output the value of a field with Text.  

You want to show 'Lot No 347', where '347' is the value taken from the form.

For the first value in the list - lot01-value  - you will therefore use 

Lot No: {lot01-value}

If lot01-value is empty then the email will still 'Lot No:' in the output.

You can hide the 'Lot No:' word by using an {if} statement to hide the text if there is no value - as follows:

{if {lot01-value}}Lot No: {lot01-value} {/if}

Now 'Lot No: ' wil only show in the email if there is a value in the field.
