`, "single-equals-in-dynamic-odds": `
Warning: The dynamic odds notation on line number ###lineNumber### (in ###generatorNameText### generator's code) has a single equals sign instead of a double-equals sign. A single equals sign is used to put a value into a variable - for example age = 10 means "put the value 10 into the age variable" whereas age == 10 means "is age equal to 10?".
`, "single-equals-in-if-else-condition": `
Warning: The if/else condition on line number ###lineNumber### (in ###generatorNameText### generator's code) has a single equals sign instead of a double-equals sign. A single equals sign is used to put a value into a variable - for example age = 10 means "put the value 10 into the age variable" whereas age == 10 means "is age equal to 10?".
`, "square-brackets-wrapping-variable-name-within-square-block": `
Warning: On line number ###lineNumber### (in ###generatorNameText### generator's code), you've got a square block - i.e. some square brackets with some stuff inside. Nothing wrong with that. But inside that square block it looks like you've got another square block? Whenever you're writing stuff inside a square block, you can refer to variable and list name
directly - no need to put them inside square blocks. So instead of [[noun].pluralForm], you'd just write [noun.pluralForm], and instead of [[characterAge] + 3], you'd just write [characterAge + 3], and instead of ^[[age] < 10], you'd just write ^[age < 10], and instead of [[age] > 60 ? [oldDescription] : [youngDescription]], you'd just write [age > 60 ? oldDescription : youngDescription]. You should use normal parentheses to group calculations and conditions, like this: [(age + 1) * height] and this: [isMammal || (isReptile && isBrown)]. In fact, if you wrap list/variable names in square brackets when you're already inside a square block then this can sometimes cause all sorts of sneaky errors that are hard to "debug". Square brackets
"legally" be used within square brackets in some circ*mstances, but they have a special meaning (learn more about this on the examples page - especially the "Dynamic Sub-list Referencing" section). One final note: It's okay to use square brackets within square brackets if the inner square brackets are themselves within double-quotes, like so: [n == 1 ? "[prefix]er" : "[prefix]ers"].
`, "top-level-list-name-same-as-html-element-id": `
Warning: It looks like you have a list name on line number ###lineNumber### that has the same name as an element's id="..." attribute? If so, note that these will conflict with one another and potentially cause errors. For example if you had a list called animal, then you shouldn't have an element like this: <p id="animal">...</p>
`, "duplicate-top-level-list-name": `
Warning: It looks like you have a list name on line number ###lineNumber### (in ###generatorNameText### generator's code) that has the same name as an earlier list/import/variable?
