# Counting variable

Trying to run a series of variables through a counter loop… I cant figure out how to merge the basic variable and the number… (var1, var2, var3, etc)

Need help right after the comment, please

``````Dim variable as string
Dim var1 as string
Dim var as string
Var1 = ABCDE

Dim y as integer
Y = 1

// help here
Variable = var + y      //?????  How do I join a variable and a number to make one new variable

Do
Textfield.text = variable.totext
Y = y + 1
If y>3 then exit
loop
``````

You can’t. Use an array or dictionary.

What are you wanting to achieve with:

[code]Variable = var + y      //?????  How do I join a variable and a number to make one new variable``````

What do you want Variable to contain? If you want to concatenate an integer to a string, you’d need to do:

``Variable = var + y.totext``

Also, with:

```Textfield.text = variable.totext ```
Since textfield.text expects a string, and Variable is already a string, there’s no need to convert Variable to text using .totext.

Dont use var1, var2, var3,

Use an array

[code]Dim Var(3) as integer

Var(1) = 6
Var(2) = 9
Var(3) = 2

For x as integer = 1 to 3 //this is your loop
Var(x) = x * 2 // note Var(x) achieves the addition of Var and number
next[/code]

For starters John, a variable can be a number or a string as you may well know.

From what you posted in your original post, you declared var as a string, yet you didn’t assign it a value!

I’ve adjusted the code to a include the assignment of “Var”. btw., it’s good practice to try to stick with capitalisation. Although, as far as I’m aware Xojo doesn’t care if you code “Var1” or “vAR1” - they are treated one and the same, it’s not case sensitive. Nevertheless, it makes it easier for you and others to read if you stick to a style

[code] Dim variable as string
Dim var1 as string
Dim var as string
Var1 = “ABCDE”
var = “XYZ”

Dim y as integer
Y = 1

// shown here:
variable = var + Str(y) // This is one way to join (concatenate) a string and a number to make one new (string) variable.

Textfield1.text = variable[/code]

This works as expected using a push button and a text field. Adding a loop (to increment the number) from this point is easy enough.

If you explain more, then you’ll get better help. This is as far as I can help
