Hello,

I have a series of variables with phone numbers (in string format) that are as follows:



I would like to replace the values of the missing phone numbers with available numbers such that all missing numbers are at the trailing end of the series (ex. if there are 2 available numbers, these should be populated in t_phone1 and t_phone2 and the remaining variables should be missing". Is the best way to approach this replacing variables starting from the right most columns until the desired order is achieved?
