# COUNT

The COUNT function counts the number of items in a range.

### Syntax

COUNT(value1, ...valueN?) - > number

### Arguments

<table><thead><tr><th width="141.33333333333331">Arguments</th><th width="167">Datatype</th><th>Description </th></tr></thead><tbody><tr><td>value1</td><td>Node reference</td><td>The first node or number to be counted. This is a required argument.</td></tr><tr><td>...valueN?</td><td>Node reference</td><td>The additional nodes or numbers to be counted. These are optional arguments.</td></tr></tbody></table>

### Example&#x20;

Consider a scenario where you want to calculate the number of periods for which the simulations are performed for a \[Sales] node. That is if simulation period is between July and September, the result should be 3.

| Sim.Months | July | August | September |
| ---------- | ---- | ------ | --------- |

In order to calculate the number of periods, the following formula should be written in the \[COUNT] node:

<mark style="color:blue;">**`COUNT`**</mark>**` ``(`**<mark style="color:purple;">**`[Sales]`**</mark><mark style="color:blue;">**`.SIM_PERIODS`**</mark>**`)`**

{% hint style="info" %}
Refer[ \[NODE\]<mark style="color:blue;">**.SIM\_PERIODS**</mark>](https://docs.valq.com/model/formula-functions/math-functions/pages/bd9R41FrVkmuCJPGQLmc#node-.sim_periods)  to know more.
{% endhint %}

### Result

| COUNT |  3  |
| :---: | :-: |
