IF/THEN Formula Problems

[middas.co.uk]

Hi Everyone,

I've been having some troubles writing what I thought  would be a simple formula to control the visibility parameter based on the dimensional parameter that I've already got in place.

Basically, I wish for the visibility to remain on unless the glazing offset is greater than 175mm. so this is how I have tried to formulate this -

if(Glazing Offset, 175 mm, Standard Glazing, 1 < 2, 1 < 0)

If somebody could point out where i am going wrong that would be greatly appreciated.

If (Glazing Offset>175mm, 1=1, 1=0)

You need to use your if statement correctly; IF , THEN , ELSE

IF (Length < 3000mm  ,   200mm   ,   300mm )

too many statements here;  if(Glazing Offset     ,      175 mm    ,     Standard Glazing    ,     1 < 2    ,     1 < 0    )

Thanks for your help, the formula worked perfectly.

Thanks for this, hopefully over time I will get a better grasp of how to construct the statements.

Or you can use “not(Glazing Offset>175)”
