**dsiden**Hello.

We need to create a sales order form.This form needs to take in numerical dimensions for the product.

Some of the dimensions are dependent upon other dimensions. All the dimensions have minimums and maxium values. Can I use a formula to define a minimum or maximum value where this formula is dependent upon an input in another numerical field?

i.e.

Dimension 1 = 1000 (min = 500, Max = 1440)

Dimension 2 = 500 (min = 500, Max = Dimension 1 / 2)

Thanks

**Carina**I created a test form, where I added numeric fields, under Quick Tools menu, and then added Text field messages warning that the values must be lower than or higher than:

I then created conditions that if dimension1 value is higher/lower than max/min to show the correspondent error message:

On the condition I added the min and max fields name. You can see here how to find a field's name:

You can test and clone the demo form:
