why don't you use MsgGetText and MsgGetExplainText function to get the text you need into a string variable and then using messagebox to show it to the user.

i have written the code as shown below

&str = MsgGetExplainText(25000, 251, "Message not found");

Error (MsgGet(25000, 251, "Message not found") | " " | &str);

but iam getting error message like
error compensation comp frequency has been changed,you must enter a proposed rate
you must enter a proposed rate
the message which i have given in explain text is coming two times.
first it is concatinated with message text in message catalogue and again below explanation is getting

this is sample error message i have given ,but my error message is too long

please let me know your comments

I thought the MsgGet function would display the Message & the Explanation? Not sure you need the MsgGetExplainText().

You can try this,

&sError = "Your longer error message here";
MessageBox(%MsgStyle_OK, "Error", 0, 0, &sError);
Return;
