Keep + character at the start of string in switch function

Hi,

I am using a Tool module to set a variable using a switch function. The variable should be a phone number with a +420 prefix, but when saving a node, the “+” character on the beginning disappears.

I tried to use quotes to enclose the phone number, but they are preserved in the variable value.

Is there a way to force the + character to remain?

After save:

Hello Integrace,

If you enter +{{+}}420777555333 as the number then save, the “+“ symbol will be included in the phone number. Unfortunately, if you re-enter the module only +420777555333 will be saved, and when you save again the “+“ will be removed.
