How to concatenate a string to a field

What field type is employee ID? 

The field is a text field but I used a reg expression to only enter 5 numbers.  No calculations or incrementing are involved. Just a 5 digit department number.

And you want to do this in your form or in the workflow? 

The process goes like this:

I created a list, created the workflow and variables and the nintex form was created.

To use the department number field as an example. When the user/requestor enters info on the form, the info is placed under the corresponding list column (e.g., department number entered on the form goes under the department number column of the list).

What I want to achieve is to add/concatenate the number "100" before the department number. For instance if the department number is 23456, I want "100" placed before it (e.g.10023456). this should be consistent for all department numbers entered.

Okeydokey so I had a quick play and here is what I did:

• Column name:  DeptNo = Single Line of Text
• Nintex Form:  disconnected single line of text control called "InitialDeptNo" added to the form to capture user input for DeptNo
• Nintex Form:  calculated value control called "DeptNoConcatenation" set up as follows:
• 
• Nintex Form:  "DeptNoConcatenation" connected to "DeptNo" column in list

Just ran a test, inserted as a user department number 23456 and list saved 10023456.

I tried this too, and it is working as long as I am not hiding the calculated value field (visible = no).

Is there any possibility/best practice to do so?

hmmm not sure about best practice but I would normally "send to back" this field behind something else so that I don't have set visible = no.  seems a bit "fudgey" but it works.

Yeah, I was already considering that approach. But I thought there would be something more... elegant.
