Survey Solutions Designer conducts analysis of your questionnaire for many common problems and design errors. The following table summarizes the messages issued by the Designer when the questionnaire is compiled.
Some of these messages indicate a situation of an error, where the current
questionnaire is invalid and may not be used for data collection until the
indicated problem is fixed. For example, these are the syntax errors in
expressions (see WB0002 or WB0003 below) or duplication of identifiers of
variables (WB0026), and other similar problems.
Other messages correspond to a situation of a warning, which hint on a
potential improvement in efficiency, or a notable situation, which may be
something to evaluate in the context of a specific survey. For example,
Survey Solutions Designer may detect that the same categories are defined in
several different questions, and advise to make use of
reusable categories:
see WB0296 below. While this is not an error, it is something that will make
the management of these sets of categories easier and reduce the work for
translators of the questionnaire to other languages. Another example is a
warning about the absence of a GPS question in the questionnaire. Having the
location of the interview opens up great possibilities for data analysis,
integration, and quality control, and is easily obtainable with modern tools,
so it can very well be an oversight that it is not included, and yet it is not
mandatory and up to the author of the questionnaire to decide whether to
include it or not in a particular survey questionnaire.

| WB0001 | Questionnaire must contain at least one question. | |
| WB0002 | Validation condition has a syntax error. | |
| WB0003 | Enabling condition has a syntax error. | |
| WB0004 | Variable cannot have empty expression. | |
| WB0005 | Variable expression has length more than {0} characters. | |
| WB0006 | Only one GPS question could be marked as identifying | Means that only one GPS location question may be placed to the cover page. Since different questionnaires may have different variable names for the GPS questions, Survey Solutions picks the location question not by variable name, but by position (first GPS location question in the cover page) when drawing the map dashboard. Hence this restriction. Additional GPS location questions may be placed in other sections of the questionnaire. |
| WB0007 | Multi select yes/no question can't be linked | |
| WB0008 | It is not allowed to use substitutions in variable label | |
| WB0009 | Roster size question is missing. | |
| WB0010 | Macro has invalid name. | |
| WB0011 | Linked question references a nonexistent question. | |
| WB0012 | Linked question references a question type that is not supported. | |

| WB0237 | & is used in expression. Make sure you understand the difference between & and && operators. In most cases, use &&. | |
| WB0238 | | is used in expression. Make sure you understand the difference between | and || operators. In most cases, use ||. | |

Sometimes questions can be understood in context, such as the "Other (specify)" requirements in categorical questions usually result in "Please specify the 'other'" in the following question. If you don't like the warning, make the questions distinct by clarifying the question "Please specify the other food type" or "Please specify the other source of fertilizer". |
