errortext(
errortext(
EXPRESSION
)

The errortext( function evaluates an expression, but returns only the error message generated (if any).

Parameters

This function has one parameter:

expression – expression that may generate an error message.

Description

This function allows you to to determine the error message of an expression. Panorama uses this for things like reporting errors in the Find/Select dialog. If the expression works without an error, this function returns `""`. But if there is an error, the error message is returned.

    errortext(2) ☞ ""
    errortext(2+a) ☞ "Field or variable [a] does not exist"
