 This error occurs in an MSBuild project file when a number is expected in a condition expression, but the expression evaluated to a non-numeric value.
 
+### Check numeric values
+
+This error can also be generated if there's a problem with setting a numeric value. The root cause might be another error, such as an installation issue. For example, if a version number of an installed tool is used in a condition expression, but the tool isn't installed.

 ## Resolution
 
 If the error occurs in your project file, check the project file for syntax errors and other problems. For more information about the syntax, see [MSBuild conditions](../msbuild-conditions.md).
 
 Review the MSBuild properties and confirm you're using them as expected. Check the properties in the condition expression, especially properties with a numeric value, and confirm the values are numeric and use the correct syntax.
