Joining two formulas

[Norman_Glenn]

Hi was woundering if any can help me. I have to formulas that work when used individually. What i need to do is join them together.. this is my two Formulas.
=if(isnumber(search("cardboard",E5))*AND(D5="WT"),"WTC",D5) 2nd one is similar =if(isnumber(search("cardboard",E5))*AND(D5="NT"),"NTC",D5)

if joining of the two formulas doesn't cause a problem. Just use OR.@Norman_Glenn

You may simplify a bit

=D5 & IF(ISNUMBER(SEARCH("cardboard",E5))*((D5="WT")+(D5="NT")),"C","")
