Problem with value in loop

[enriweb77]

Hi everyone,
I can’t update the value of a variable inside a loop.
In the screenshot you see my example.
The initial value of txCognome is ‘Rossi’ so the loop should add 25 ‘+’ to the string.
Instead drawing the variable after the loop leaves it with the original value ‘Mike’

How do “Name” and “Global Name” work and how to use it and when?

This is a great question. I’ve found that you need Global Name to reference the value outside of a repeat or loop where it’s been set. My habit is to fill in both Name and Global Name with the same name on everything but I’d love to know if that is bad practice. If it is a perfectly good way to go then it does beg the question, “why don’t we just have one field which is the global one?”

Use Global Name and don’t use the same names for both fields

What is the purpose of this expression: {{txCognome+'+'}}?

[enriweb77]

it was just a test to see if it concatenated the string to the original variable.
I should actually add some blanks

Add the same global name for these two steps:

YES it works now, I only set the global name
