How to Increase Value By 1

[dantrader$]

Dear Forum,

This will come off as one of the most trivial questions in this group, however I have not been able to find a valid way to get a variable to to increase its value by one. I have tried: i=i+1; , i+=1; , i++; however all of these methods are throwing up the error "Already Assigned i". If anyone has solutions on how to resolve this issue, let me know, otherwise I am happy to provide the explicit code where the error is occurring. Thank you for your time and I look forward to hearing back soon.

use an offset of 1 , [1] , to read a previous value of a variable and add 1 to it.
def a = a[1] + 1;

Dear Halcyonguy,

Thank you for the reference! Unfortunately after implementing the following code, it is still not able to update the value inside of an if statement. Is there a work around or syntactical edit I can make in order for the following code to work? :
def z=0;
if (z == 0)
then {
def z = z[1] + 1;
}
else {}
plot a=z;

answers would come quicker to people who post complete info and questions up front.


can't use a def within a if then.
can't use an output function within an if then. (plot, addlabel,...)
when using a def before an if then, it can't be set to a value.

def bn = barnumber();
def z;
if bn == 1 then {
z = 1;
} else if !isnan(close) then {
z = z[1] + 1;
} else {
 z = z[1];
}

plot a=z;

Dear Halcyonguy,

I appreciate the followup! I have found that
def z;
if (z==0)
{z=z[1]+1;}
else{z=z[1];}
works as well!
Unfortunately, I am now running into a similar problem with updating values within nested if statements. My apologies for the double follow up, but if you have any insight as to how I can solve the following problem, it would be truly appreciated:

def m;
def z;

if ('condition')
then {
if ('subcondition1') {
m = m[1] + 1;
} else {
}
if ('subcondition2') {
z = z[1] + 1;
} else {
}
}
else {
}

The problem is that I cannot update the values of m and z. Thank you so much for your time, and I look forward to reading your response!
