Remove or edite the default error message

[kerolos samir]

Hi team 
Is there any way to modify this error message in the screen 
Or remove it and show another one with a client script 

[kerolos samir]

this is the client script that i am using 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if (isLoading || newValue === '') {

return;

}

if (!Number(newValue) || !Number(oldValue)) {

getMessage('Maximum waiting time should be Number', function(msg) {

g_form.showErrorBox('max_waiting_time', msg);

});

}

//Type appropriate comment here, and begin script below

}

try below:

if (!Number(newValue) || !Number(oldValue)) {

g_form.hideFieldMsg('max_waiting_time');

getMessage('Maximum waiting time should be Number', function(msg) {

g_form.showErrorBox('max_waiting_time', msg);

});

[kerolos samir]

it didn't work 
what works is this 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if (isLoading || newValue === '') {

return;

}

if (!Number(newValue) || !Number(oldValue)) {

getMessage(`Maximum waiting time should be Number ${newValue}`, function(msg) {

g_form.hideErrorBox('max_waiting_time');

g_form.showErrorBox('max_waiting_time', msg);

});

}

}
But the could not parse message appear as a flicker in the ui before the second one replaces it

Try this combination:

g_form.hideFieldMsg('max_waiting_time');

if (!Number(newValue) || !Number(oldValue)) {

g_form.hideFieldMsg('max_waiting_time');

getMessage('Maximum waiting time should be Number', function(msg) {

g_form.showFieldMsg('max_waiting_time', msg);

});

@kerolos samir I am not able to reproduce this error message in OOB. Which field is this? 

Is this a OOB or custom field or variable.

1. When I tried it on custom integer field , it turns to 0 as I enter any string value.

2. On string variable with number regex error is "Not a number".

Can you explain how to reproduce this?
