How can i veiw error message based on some condition

[#1]

Hi Friends,

I need to show a error message based on a condition. I know it can be done by Custom Error message. But I don't know how to make a conditional statement.

Eg:

I have a date field if enter the wrong date means it show me pls enter the valid date....

This generic plan can help you in the creation of a solution:

• Define what constitutes an iinvalid value (e.g. bounds? invalid month-day-year-values? etc.)
• Translate these rules into a logical expression that checks whether a field is inside/outside these bounds
• Add this expression to an IF() function that displays an error message in a text box whenever the conditions are met.

Note that QV does not have an IsDate() test function. But you can easily use date#() for that. If date#() returns NULL, then either the values ( e.g. '99/99/9999') or the format (e.g. '1/ABC/2015') of the parameter or both are wrong.
