I'll try mike but its a bit hard hard to explain with what I'm trying to achieve.
I'm trying to change the text in an IF statement but there is a variable in the if statment which needs to be chnaged
for example this is what I've got.
sf1:=if(design="LRFD","Resistance factor for shear phi0.9", "safety factor for shear omega 1.67")
however phi0.9 and omega 1.67 are variables, this is the bit I'm struggling with, these bits of text need to change based on a selection from the user.
