Project Budget (USD)
$30 - $250

Project Description:
I offer following project:
I have a vtiger Installation version 5.4.0.
My E-Mail templates do not accept the variable $custom-currentdate$ (the date will not be shown in the E-Mail, insted only the variable, f. e. "$custom-currentdate$").
Neither my E-Mail templates do accept variables for personal LastName.
Within the search for leads or contacts the presetting of leads and contacts is "Lead no." (Lead number).
I would like to change it to "last name".
The sorting of leads and contacts in the dashboard should be descending instead ascending (the latest values above).

I get an error if i want to make a backup in Vtiger. Alternatively mysqldumper can be installed to do this job.
The listview of leads and contacts enable to display predefined values if the mouseposition is within the field LastName (tooltip management).
I would like to see this informations as well if I make a global search (searchfield at the top).
I define a filter for specific contacts, I enter, modify and save an existing contact.
Afterwards I cannot call the filter through the UndoButton of the browser. I get the message "this document is no more´s not in the browser-cache available" (see attachment).
If I create an event and want to repeat it yearly, the definition of the calender date will not be saved. If I enter again the entry the date field is empty.
A message of my contactform shall be translated from "successful" to "Anfrage versendet".
A message of my contactform shall be translated from "" This field is mandatory" to "Bitte Pflichtfelder ausfüllen"
