how do i add zeroes at the beginning of a string so the total length will be 10 digits

Hi!

You can achieve this by using a loop:

Keep adding a "0" character to the beginning of the string representing your value (using the "set variable" advanced command) until the length is 10 exactly. Please see the below/attached screenshot.

Hope that answers your question!

Kind regards,

Theo

thank u for the idea

is there an option of doing this without the loop?

I don't know why but I'm sure that there is a way without it...

Yes, actually, but I was too tired it seems yesterday to come up with it and a colleague pointed it out this morning (guess I needed more coffee ? 😞

Just use two advanced commands:

1. Add "0000000000" to the beginning of your variable/value
2. Then just get the last (from the right) 10 characters using the "find" command and a regex "[0-9]{10}$"

See the below screenshots and thanks to @Artur Martirosyan​ for the pointer on this!
