Hi All, Below script will help if you conditionally want to restrict the number of rows in multi-variable set.

//This script will allow you to add 5 rows in MVS if you selected 5 in field A and so on.

Field A - Select box variable with choice values (1-10)

Field B - Multi-Variable set

On-Change catalog client script on field A.

------------------------------

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

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

return;

}

//Type appropriate comment here, and begin script below

var ServerSize = g_form.getValue('Field_A'); //Select box variable

function setMaxRowSize (sysIdMRWS, limit) {

var tableVariable = typeof tableVariableCache !== "undefined" &&

tableVariableCache["table_variable_buttons_" + sysIdMRWS] != null ?

tableVariableCache["table_variable_buttons_" + sysIdMRWS] :

typeof table_variable !== "undefined" ? table_variable: null;

if (tableVariable != null) {

if (typeof tableVariable.setMaxRowSize === "function") {

tableVariable.setMaxRowSize(String(limit));

} else {

tableVariable.maxRowSize = limit;

}

}

}

setMaxRowSize("feb9ad834fe9f300b8580ab18110c719", ServerSize); //sys_id of MVS

}

Hope this helps.

Thanks
