Important Reminders

• All keywords in the tag syntax must be in uppercase. There must be no spaces except within check values and field names.
• Parts of template between neighboring tags must not exceed 32,000 characters in size. If you do have a part exceeding this limit, break it up by inserting a null tag, such as <!--[[Null_Break]]-->. No contents need to be provided for this tag.
• Anything between tags will be copied to the output file, so you must not put in line breaks or spaces where you do not want them in the output. However, it may be easier to develop IF or CASE structures in your template by putting the tags on separate lines with indentations. This is certainly okay, except that when you are satisfied with your template you must remove those spaces and line breaks not supposed to be present in the output file.
• There are good practices that can reduce errors in constructing control structures in your templates. The key is to build them layer by layer. Start each layer by adding the complete structure without the comparison expression, such as <!--IF()--><!--ELSE--><!--ENDIF-->. This prevents the common errors of improperly closing the structure or syntax. Next you fill in the comparison expression. If you now decide that the ELSE tag is not needed, you may remove it. With this layer completed, you may then in a similar manner add the next layer between the IF and ELSE tags, and afterwards a layer between ELSE and ENDIF, and so on. The same idea is applicable to CASE structures or even a mix of LOOPs, IFs and CASEs.
