Hello all good people

I need some help compiling a formula inside Monday and General caster

I need to cook together an IF statement that does something like this …

I already have a formula (F1) that combines two items into one (Concatinate) and the result is a mix of letters and numbers (I.e. MSUB12000013 and AA = MSUB12000013AA

The number of letters and digits are supposed to be 14

So the IF statement I am looking for is something like

IF “Formula 1” creates a result with 14 numbers and digits then display the result of "Formula 1, or else display nothing …

Hope some formula wiz can assist me with this

Kind regards Nils
